  11. 11. 12 New User Interface for Operations1.1 InventorCAM2008 R12 offers you a new enhanced interface for milling and turning operations. In the new interface, the single-page dialog box of the previous interface is divided into a number of pages, each handling a specific set of parameters (e.g. Geometry, Tool, Levels, Technology, etc.). The list on the left side of the dialog box enables you to switch between the different parameters pages. You may switch between the new and the previous single-page interface by using the User Interface page of the InventorCAM Settings dialog box. To work with the single- page interface, choose Single-Dialog. To switch to the multi-page interface, choose Multi-dialog. In this mode, you may also set a keyboard shortcut for switching between pages in the multi-page dialog box; click on the Switch Items Hotkey box and press a required key or a combination of keys you want to use as hotkeys for switching. Technology Geometry parameters Parameter illustration Parameters page Info Tool parameters Machining levels parameters Link parameters Operation name Operation buttons Template Technological parameters Miscellaneous parameters
  12. 12. 1.General 13 Support of the 3D Connexion SpaceNavigator1.2 InventorCAM2008 R12 provides you with the support of the SpaceNavigator 3D mouse by 3Dconnexion (www.3dconnexion.com). This device enables you to rotate, pan and zoom the CAD model during all the stages of the CAM-Part definition. Using the SpaceNavigator enables you to significantly speed up the geometry definition process and simplifies the model and tool path viewing during such simulation modes as HostCAD, Rest Material, SolidVerify, RapidVerify and Machine Simulation.
  13. 13. 14 Operation summary in InventorCAM Manager1.3 InventorCAM2008 R12 providesyouwiththepossibility to obtain thesummary of a specificoperation directly from the InventorCAM Manager, without opening the operation. The Info command located in the right-click menu available on a specific operation in the InventorCAM Manager displays the Info dialog box. This dialog box displays the summary information of the selected operation: Tool information (diameter, corner radius, taper angle and lengths); Operation Tool data (feeds and spin) and Levels (Upper level, Depth and Step down). The icon located in the title bar enables you to pin/unpin the Info dialog box.
  14. 14. 1.General 15 Summarizing the part data in the tool sheet documentation1.4 InventorCAM2008 R12 provides you with an advanced option to summarize the CAM- Part information by generating a tool sheet documentation in the PDF format. Definition of tool sheet parameters1.4.1 The Tool Sheet command is available for the complete CAM-Part (in the right-click menu available on the CAM-Part header) or for separate operations (in the right-click menu available on the operations). The Tool Sheet Extra Parameters dialog box is displayed. This dialog box enables you to manage the content of the documentation PDF file. In this dialog box, you can attach a logo file (in the BMP format) to your tool sheet, define your own variables and values that will be inserted into the tool sheet, add comments and notes relative to your part, and decide whether you need the full version of the information sheet or only particular sections, such as Operations summary or Tool Table. The Show Last Tool Sheet command enables you to display the last generated tool sheet for the current part, instead of generating it anew. The Tool Sheet Extra Parameters dialog box is displayed so that you can define which sections of the last tool sheet you want to display.
  15. 15. 16 The output PDF file1.4.2 The output PDF file consists of the following sections: Main page This section summarizes general information about the CAM-Part, including its picture and the comments and notes you have added. Tool table This section displays the list of the tools used for the operations of the current CAM-Part, with their parameters and illustrations. Part picture Part notes Company logo Part definition Part properties Part name
  16. 16. 1.General 17 Operations summary This section summarizes the operations defined for the current CAM-Part. Fixtures This section shows how the part must be fixed on the CNC machine table.
  17. 17. 18 Opening of PRT files by double-clicking1.5 In the previous versions of InventorCAM, it was only possible to open a PRT file by using the InventorCAM submenu in the main menu of Autodesk Inventor, i.e. to open a CAM-Part file, you needed to load Autodesk Inventor, click InventorCAM, Open, and then choose the required file from the CAM-Parts browser. InventorCAM2008 R12 provides you with a time-saving possibility to open a PRT file by double-clicking on the file name in any location where it is saved.
  18. 18. 1.General 19 3D geometry selection1.6 In previous InventorCAM versions the Select/Unselect radio button was used in dialog boxes for 3D geometry selection (solids, surfaces and faces). This radio button switches the system between the selection and unselection modes. InventorCAM2008 R12 provides you with an improvement of the selection/unselection of the 3D geometry. This improvement is based on automatic toggling between modes: a click on the model entity selects it, while the next click on the selected entity removes the selection. The Select/Unselect radio buttons are therefore removed from the relevant dialog boxes (3D Geometry dialog box, 3D Box dialog box, Select faces dialog box, etc.)
  19. 19. 20 Templates1.7 InventorCAM2008 R12 provides you with the functionality of templates that is useful for simplifying the repetitive tasks in the CNC programming. InventorCAM enables you to save the operation data as a template and load it into a new operation of the same type. InventorCAM enables you also to specify the default operation template that is used for each newly created operation of the appropriate type. InventorCAM enables you also to define and use a Process Template, which is a template of a series of operations that executes a specific machining task. Operation Template1.7.1 InventorCAM enables you to create an operation template by saving an already defined operation. The saved template can be used later for a new operation definition. The saved template data does not include the geometry, which must be defined after loading the template. The saved template can optionally include the tool data. The Template section is added into each InventorCAM Operation dialog box. This section provides you with the following functionality:
  20. 20. 1.General 21 Save Template The button enables you to save all the data (except for the geometry) of the current operation as a template. The Template Manager dialog box is displayed. This dialog box enables you to choose the name for saving the template. The template is saved in the location defined in the Templates Directory parameter in the Part Settings dialog box (see topic 1.7.4). The Operation Templates table displays all the Operation Templates located in the Templates Directory and their types. The Include tool data check box enables you to include the tool data in the saved template. Type the name in the Template edit box and click on the OK button to confirm. If a template with the defined name already exists in the current location, InventorCAM displays the following warning message: When you confirm this warning by the Yes button, InventorCAM overwrites the existing template with the new one. When you click the No button, the Template Manager dialog box is activated again providing you with the possibility to choose a different name for the template.
  21. 21. 22 InventorCAM enables you also to saveanexistingoperationasOperation Template from the InventorCAM Manager, using the Create Template command from the right-click menu available on single operations. This command displays the Template Manager dialog box which enables you to save the template data as described earlier.
  22. 22. 1.General 23 Load Template The button enables you to load a specific template into the current operation. The Template Manager dialog box is displayed. This dialog box offers you the templates located in the Templates Directory determined by Part Settings (see topic 1.7.4). TheTemplate Manager dialogboxdisplays only the templates whose type is suitable for the current operation. Choose the necessary template and click on the OK button to confirm the operation. When the template is loaded, all the current operation data are substituted with the data from the template. When a template is loaded into the operation, its name is displayed in the edit box in the Templates section. A tool tip message is available when you place the mouse cursor over the edit box; the tool tip message displays the full path to the loaded template. When any of the operation data is modified after a template is loaded, the template name in the edit box is marked with the asterisk sign (*).
  23. 23. 24 InventorCAM enables you also to create a new operation from an existing template, directly from the InventorCAM Manager using the Add Operation from Template command from the right-click menu available on the operations header or on single operations. This command displays the Template Manager dialog box that enables you to choose an existing template as described earlier. In this case the Template Manager dialog box displays all the templates existing in the Templates Directory regardless of their type. When the dialog box is confirmed by the OK button, InventorCAM inserts the chosen Operation Template into the InventorCAM Manager tree. The inserted operation is incomplete sinceithasnogeometryandtooldefined (if the initial Operation Template used for the operation creation had no tool). The incomplete operations are marked with red color. Since the incomplete operation has no geometry, its tool path cannot be generated. In order to complete the operation definition, you have to define its machining geometry and tool (if the latter is necessary). During the creation of a new operation from an Operation Template, InventorCAM assigns the Machine Coordinate System #1 (Position #1) for the newly created operation. During the operation editing, this Coordinate System can be changed.
  24. 24. 1.General 25 Tool search When an operation template is loaded, InventorCAM checks for the tool data in the template; if the tool data was saved in the operation template, the tool search is performed according to the following rules: • When the operation template uses a tool defined as Permanent, the search for this tool is performed using the tool number only. At the first stage, the tool search is performed in the Part Tool Table. If the tool with the defined number is not found in the Part Tool Table, InventorCAM performs an additional search in the Current Tool Table. If the tool with the defined number is found in the Current Tool Table, it is copied into the Part Tool Table and chosen for the operation. If the tool is not found in the Current Tool Table, InventorCAM displays the following error message: When you confirm this message with the OK button, InventorCAM returns you to the operation dialog box in order to define a tool. • When the tool in the operation template is not defined as Permanent, InventorCAM performs the search using the tool parameters. The tool parameters used for the tool search are defined in the Tool search page of the InventorCAM Settings dialog box. The tool search is performed in the Part Tool Table. If a tool with the same definition as in the template is not found in the Part Tool Table, InventorCAM performs an additional search in the Current Tool Table. If a suitable tool is found in the Current Tool Table, it is copied into the Part Tool Table and chosen for the operation. If the tool is not found in the Current Tool Table, a new tool with the parameters defined in the template is created in the Part Tool Table. InventorCAM automatically assigns the first unused number for the newly created tool. When you load a template containing tool data into an operation that already has a defined tool, InventorCAM displays the following message: When you confirm this message, InventorCAM replaces the tool already defined in the operation with the tool defined according to the template.
  25. 25. 26 Process Template1.7.2 InventorCAM2008 R12 enables you to define and use a Process Template, which is a template of a series of operations that executes a specific machining task. Such capability enables you to store a complete sequence of operations as a Process Template and apply it for the machining of similar cases. Define Process Template To create a Process Template, select in the InventorCAM Manager all the operations intended to be included in the Process Template and choose the Create Template command from the right-click menu available on single operations. This command displays the Template Manager dialog box that enables you to save the chosen operations as a Process Template. This dialog box displays all the existing Process Templates in the Templates Directory; the Process Templates names are listed in the Template Folders section under the Process Templates header. The sequence of operations comprising the template is displayed in the Operation Templates table.
  26. 26. 1.General 27 The Include tool data check box enables you to include the tool data in the saved Process Template. To save the selected operations as a new Process Template, enter the name in the Process Template edit box and confirm with the OK button. If a Process Template with the defined name already exists in the current location, InventorCAM displays the following warning message: WhenyouconfirmthiswarningbytheYes button,InventorCAMoverwritestheexisting Process Template with the new one. When you click on the No button, the Template Manager dialog box is displayed again providing you with the possibility to choose a different name for the Process Template. The Template Manager dialog box provides you with the capability to create an empty Process Template and copy to it a number of Operation Templates from different Process Templates. See topic 1.7.3 for more details. Use Process Templates InventorCAM enables you to insert the Operation Templates contained in a Process Template into a CAM-Part, converting them into regular InventorCAM Operations. To insert a Process Template into the CAM-Part, choose the Add Operations from Process Template command from the right-click menu available on the Operations header or on the single operations in the InventorCAM Manager.
  27. 27. 28 This command displays the Template Manager dialog box which enables you to choose an existing Process Template to be inserted. During creation of a new operation from the Process Template, InventorCAM displays the CoordSys selection dialog box that enables you to choose the Coordinate System for the created operations. The inserted operations are incomplete; this means that the operations have no geometry and tool defined (if the initial Operation Template used for the operation creation contained no tool data). The incomplete operations are marked with red color. Since the incomplete operations have no geometry, their tool path cannot be generated. In order to complete the definition of these operations, you have to define the machining geometry and tool (if the latter is necessary) for each operation.
  28. 28. 1.General 29 1.7.3 Manage Operation/Process Templates The Manage Templates command located in the InventorCAM menu enables you to manage your Operation Templates and Process Templates using the Template Manager dialog box. The Template Folders section contains Templates and Process Templates. When the Templates header is selected, all the Operation Templates located in the Templates Directory are displayed in the Operation Templates table. All the Process Templates located in the Templates Directory are listed under the Process Templates header. When a Process Template is selected, all the Operation Templates included in it are displayed in the Operation Templates table.
  29. 29. 30 InventorCAMenablesyoutomanage theProcessTemplatesusingtheright- click menu available on the Process Templates header or single Process Templates. This menu provides you with the following commands: • New Process Template. This command enables you to create a new empty Process Template. • Rename. This command enables you to rename an existing Process Template. • Delete. This command enables you to delete an existing Process Template. InventorCAM enables you to manage Operation Templates with the right-click menu which is available on the Operation Templates in the Operation Template table. This menu is available for the standalone Operation Templates located in the Templates Directory and for Operation Templates included into Process Templates.
  30. 30. 1.General 31 The menu provides you with the following commands: • Create Process Template. This command enables you to create a new Process Template; the current Operation Template is added to this process. • Copy. This command enables you to copy the current Operation Template into the clipboard. • Paste. This command enables you to paste the Operation Template from the clipboard. The Operation Template is inserted into the chosen location (either into the current Process Template or as a standalone Operation Template into the Templates Directory). • Edit. This command enables you to load the chosen Operation Template for editing. When a template is loaded, InventorCAM displays an appropriate operations dialog box with the template data. InventorCAM enables you to edit all the parameters and options of the template, except for the geometry and the coordinate system. The button enables you to save the template data using the Save template dialog box. • Delete. This command enables you to delete the active Operation template.
  31. 31. 32 1.7.4 Defaults & Settings InventorCAM Settings The Template Defaults page is added to the InventorCAM Settings dialog box. This page enables you define the default location of the Operation and Process Templates and to specify the default templates that are used for each new operation. InventorCAM Template Directory The InventorCAM Template Directory section enables you to define the default location for InventorCAM Operation and Process Templates. You can define the path by entering it in the combo-box or by using the Browse button. In case the chosen folder does not exist, InventorCAM displays the following message: • The Create button enables you to create the folder with the specified location and set it as the InventorCAM Template directory.
  32. 32. 1.General 33 • The Browse button displays the browser dialog box that enables you to choose another location for the InventorCAM Templates directory. By default, the Template directory location is ..TablesMetricTemplates for Metric units and ..TablesInchTemplates for Inch units. Operation default templates The Operation default templates section enables you to assign default templates for operations. The templates are divided between four tabs: • The 2.5D Milling tab contains the 2.5D milling operations. • The 3D Milling tab contains the 3D milling operations. • The HSM tab contains the HSM operations. • The Sim. 5-Axis tab contains the Sim. 5-Axis operations. Each tab contains a table that enables you to define thedefaulttemplatesof each InventorCAM operation. When the default template use is activated for a specific operation, the Template column enables you to use the suitable template with the combo-box. When the template use is activated for an operation type, each new operation of this type will be started with the data of the specified template.
  33. 33. 34 Templates activation/deactivation When user deactivates template use for an operation, the Template column combo-box is disabled. When you activate template use for an operation type, InventorCAM performs search for suitable templates of this type in the InventorCAM Template Directory. The combo-box is filled with the names of the found templates; the first of them is automatically chosen. In case of absence of suitable templates, InventorCAM deactivates the use of templates for this operation. Changing the InventorCAM Template Directory When you change the InventorCAM Template Directory, InventorCAM performs search for suitable templates for all operations with the activated default template use. When a template for some operation is not found, InventorCAM deactivates the default template use. Found templates are inserted into the related combo-box. The first found template name is displayed. The templates search is not performed for the operations where the templates use is deactivated. Creating templates sets (working style) Consider a folder containing a set of templates. This set contains only one template for each specific operation; all the operations are thus covered by templates. This set is customized for a specific application (e.g. Mold machining). Consider an additional folder containing a set of templates for another application. By switching between these folders for the InventorCAM Template Directory, InventorCAM switches templates for all the operations. This enables you to quickly choose a templates set for a specific application.
  34. 34. 1.General 35 Part Settings InventorCAM enables you to customize the template default settings for a specific CAM-Part using the Template Defaults page of the Part Settings dialog box. During the CAM-Part definition, the Part settings for Template defaults are copied from the InventorCAM Settings. The behavior of this page is similar to the behavior of the Template Defaults page of the InventorCAM Settings dialog box.
  35. 35. 36 Defining Transform position by picking on the model1.8 InventorCAM2008 R12 enables you to define the positions for operations transformation by picking on the model. This functionality is implemented for Move and Translate by List options. When you choose the Move item from the Transform menu in InventorCAM Manager, the Move Operations dialog box is displayed. This dialog box enables you to define the move position by entering the offset values along the axes or by picking on the model. To define the move position by picking on the model, activate the Move Operations dialog box and click the necessary position on the design model. The coordinates of the picked position are displayed in the offsets edit boxes. The picked positions are not associative to the solid model. The behavior of the Translation list dialog box is similar; the coordinates of the picked position are displayed in the Offset value edit box. The Enter button enables you to confirm the picked position and include it into the positions list. The picked positions are not associative to the solid model.
  36. 36. 1.General 37 Automatic synchronization and calculation1.9 In previous versions, InventorCAM provided you with the possibility to automatically perform the synchronization check. During this check the unsynchronized geometries and operations based on them were detected. InventorCAM2008 R12 provides the additional capability to perform the synchronization and tool path calculation automatically for detected unsynchronized operations. The Synchronization page of the InventorCAM Settings dialog box has two new options. The Synchronize automatically and Calculate operations after the synchronization options are added under the Check synchronization always option (this option enables you to perform the synchronization check automatically).
  37. 37. 38 Synchronize automatically The Synchronize automatically option enables InventorCAM to perform the geometries synchronization automatically. This option is available only when the Check synchronization always option is chosen. When the Automatically synchronize geometries check box is selected, InventorCAM performs the synchronization check and then automatically synchronizes all the unsynchronized operations and geometries. When the synchronization fails for certain operations or geometries, InventorCAM marks the operations/geometries with an exclamation mark and deletes the operations tool paths; such operations are marked with asterisk. Calculate operations after the synchronization The Calculate operations after the synchronization option enables you to automatically perform the calculation of the synchronized operations. This option is available only when the Synchronize automatically check box is selected. When the Calculate operations after the synchronization check box is selected, InventorCAM automatically calculates all the synchronized operations; the operations marked with the exclamation mark are not calculated.
  38. 38. 1.General 39 Changing the tool and tool data directly from InventorCAM1.10 Manager Changing tool1.10.1 In previous InventorCAM releases, changing the tool for a particular operation could be performed only via the operation dialog box. InventorCAM2008 R12 enables you to change tools directly from InventorCAM Manager. The Change Tool option is added into the right-click menu available on the operation entries in the tree. This option displays the Tool dialog box that contains the parameters of the current tool and enables you to choose another tool for the operation.

  41. 41. 42 Closing geometry chains by extending chain entities2.1 The Curve option commonly used for geometry chains selection enables you to select a continuous geometry chain by picking its successive entities. During the geometry definition InventorCAM detects the gaps between selected entities and provides you with the capability to close them, taking into account the Gap Minimum and Gap Maximum parameters defined in the InventorCAM Settings. When the detected gap is smaller than the Gap Minimum tolerance,InventorCAMautomaticallyclosesitbyextending/ shortening chosen entities up to their virtual intersection point.WhenthegapisgreaterthantheGap Minimum tolerance but smaller than the Gap Maximum tolerance, InventorCAM displays a prompt message asking you if you want to close the gap. If you confirm, InventorCAM automatically closes the gap by extending/shortening chosen entities up to their virtual intersection point; if you cancel, InventorCAM does not close the gap and unselects the last entity. When the gap is larger than the Gap Maximum tolerance, InventorCAM does not accept the chosen entity and displays a warning message. InventorCAM2008 R12 provides you with the Curve + Close Corners option of the chain geometry selection. This option enables you to close the gaps between successive chain entities irrespective of the Gap Minimum and Gap Maximum values.
  42. 42. 2. Geometry 43 When a gap is detected between two successively selected entities, InventorCAM continues the chain by virtually extending the selected entities according to the direction of the first entity up to a virtual intersection point between the two entities. If there are several possible intersection points, the point closest to the last vertex of the first selected entity is chosen. If an intersection point cannot be found by extending one or both selected entities, the following message is displayed. Splines and arcs are extended by lines tangential to the arc/spline at its end point. Associativity and synchronization When the model used for the geometry definition is modified, InventorCAM enables you to synchronize the geometry with the updated model. During the synchronization InventorCAM handles the gap areas closed using the Curve + Close Corners option by regenerating the extension of the chain elements so as to close the gaps. First selected entity Next selected entity
  43. 43. 44 Geometry modification for specific operation2.2 InventorCAM enables you to share geometries between a number of InventorCAM operations. InventorCAM2008 R12 provides you with the additional capability to modify a shared geometry specifically for each operation; this includes assigning different values to the geometry Extension, Offset and Define Start parameters. The geometry modification also includes choosing which geometry chains are active in the operation (in case of multiple chain geometry). The modification is relevant only for the current operation and does not affect other operations where the geometry is used. The geometry modification is supported for the Profile, T-Slot and Translated Surface operations. The Geometry button is added to the Modify section of the Technology page of the operation dialog box. This button displays the Modify Geometry dialog box. This dialog box enables you to perform the geometry modification for the current operation. Tool side This option enables you to define the tool position relative to the geometry.
  44. 44. 2. Geometry 45 Chains This section displays the list of all the geometry chains participating in the current geometry. The check box located near each chain entry enables you to include/exclude the chain from the geometry of the current operation. A right-click menu is available on the elements of the list. This menu enables you to perform the following actions: • Check all. This command enables you to check all the chains. • Uncheck all. This command enables you to uncheck all the chains. • Invert check states. With this command the state of the check boxes of all the chains will be reversed. • Reverse. This command enables you to reverse the direction of the chain. • Reverse All. This command enables you to reverse the direction of all the chains.
  45. 45. 46 Extension This section enables you to define the extension for the selected chain. The Start and End parameters define the start and end extension lengths. The extension is performed tangentially to the chain entities at the start and end points of the geometry chain. The start and end elements are determined according to the chain direction. When a negative value is defined, InventorCAM shortens the chain by a distance measured along the chain elements. InventorCAM enables you to define the Start and End parameters by entering the values in the edit box or by picking on the model (when the cursor is placed in the edit box). The Apply to all button enables you to apply the extension defined for the selected chain to all the chains of the geometry. Geometry chain Start extension End extension
  46. 46. 2. Geometry 47 Modify offset This section enables you to define the offset for the selected chain. Machining is performed at the specified offset. InventorCAM enables you to define the Modify offset parameter by entering the values in the edit box or by picking on the model (when the cursor is placed in the edit box). The Apply to all button enables you to apply the Modify offset defined for the selected chain to all the chains of the geometry. The direction of the Modify offset for the open contours is defined according to the chain direction. A positive Modify offset value adds the offset to the right side the of the chain according to the chosen chain direction. A negative value adds the offset to the left side the of the chain according to the chosen chain direction. Geometry chain Modify offset Modified chain Positive Offset Negative Offset Geometry Chain
  47. 47. 48 For closed contours, a positive Modify offset value adds the offset to the outer side of the geometry; a negative Modify offset value adds the offsets to the inner side of the geometry. The Take 1/2 from selected offset option enables you to add the offset to the chain by half of the defined offset value. In the part shown below the central pads should be machined by a single straight cutting pass in the middle of the pad. The geometry is defined on the edge of the pad and then the offset is added by using the picked position at the opposite edge and the Take 1/2 from selected offset option. Positive Offset Negative Offset Geometry Chain Modified geometry Geometry Picked offset position
  48. 48. 2. Geometry 49 Define Start This section enables you to shift the start position of closed chains. For open chains, this section is disabled. The shifting of the start point is defined as percentage of the chain length. InventorCAM enables you to define the start position shifting by entering the Shift value in the edit box or by picking the position on the model. The Apply to all button enables you to apply the Shift value defined for the selected chain to all the closed chains of the current geometry. The Auto next button enables you to define the start points successively for all the closed chains by picking the positions on the model. When this mode is activated, the first closed chain is highlighted enabling you to pick the start position for it. When the position is picked, InventorCAM switches to the next closed chain and, so on. The Resume button enables you to finish the Auto next definition of the start positions. The Set default button enables you to return the start position of the current chain to its initial state. When the Apply to all check box is activated, the Set default button returns the start positions of all the chains to their initial state.
  49. 49. 50 Automatic closing of open geometries for Pocket operations2.3 InventorCAM2008 R12 provides you with the possibility to automatically close the open geometry chains for Pocket operations. When you confirm an open chain definition for a Pocket operation in the Geometry Edit dialog box with the Accept chain button, InventorCAM displays the Close Chain message box. When you confirm this dialog box with the OK button, InventorCAM closes the chain with a line connecting the start and the end points of the chain. The Mark line as open edge check box enables you to mark the connecting line as an open edge to perform Open Pocket machining (see topic 4.11). When you click on the Cancel button, InventorCAM returns to the geometry definition and enables you to close the chain manually by the model element selection. Selected chain Connecting line
  50. 50. 2. Geometry 51 2.4 Synchronization when design model configuration changes In previous versions, InventorCAM provided you with a constant link between the geometry and the iPart configuration that was used for the geometry definition (parent configuration). With such link, switching between configurations of the iPart family did not affect the defined geometry; the geometry could be updated through synchronization only in case the parent configuration was modified. InventorCAM2008 R12 provides you with an additional functionality that enables you to synchronize the geometry when switching to another iPart configuration is performed. InventorCAM discontinues the link between the geometry and its parent configuration and establishes a new link between the geometry and the current iPart configuration. Such functionality enables you to automatically update InventorCAM geometries according to the current iPart configuration of the design model. This functionality enables you for example to perform the machining of a family of similar parts in a single CAM-Part based on a single design model and managed by iPart configurations. The geometries of this CAM-Part are automatically updated for each current iPart member configuration, providing you with an updated tool path. InventorCAM Settings The Synchronization when design model configuration changes section is added to the Synchronization page of the InventorCAM Settings dialog box. This section enables you to define InventorCAM behavior in case when switching to another iPart member configuration is performed. The InventorCAM Settings are used as default for the Part Settings of each newly defined CAM-Part.
  51. 51. 52 Part Settings The Synchronization page is added to the Part Settings dialog box. This page enables you to define InventorCAM behavior in case when switching to another iPart configuration is performed for the current CAM-Part. The Synchronization when design model configuration changes section provides you with the following options: The Keep the geometry associative with the parent configuration option enables you to keep the link between the geometry and the parent configuration. InventorCAM always keeps the geometry linked to the parent configuration (the configuration used for the geometry definition). When you switch between the iPart configurations, this does not affect the geometry; synchronization is required only in case when the parent configuration is changed.
  52. 52. 2. Geometry 53 The Associate the geometry with the current configuration option enables you to establish the link between the geometry and the current iPart configuration and perform the synchronization according to the current iPart configuration. After such synchronization the geometry is linked to the current iPart configuration until you switch to another one.

  56. 56. 3. Tools 57 End Mill/Bull nose mill/Ball nose mill3.1 The End/Rough Mill tool type used is previous InventorCAM versions is reclassified into three separate tool types: End mill, Bull nose mill and Ball nose mill, according to the Corner radius value. End mill3.1.1 A tool of this type is defined by the parameters shown in the image. Note that the Corner radius parameter used for the tool definition in previous versions is not used any more for the End Mill tool definition. The cylindrical tool arbor is added to the tool definition. The arbor diameter and length are defined by: Arbor Diameter and (Total Length - Shoulder Length). The Shoulder Length should be greater than or equal to the Cutting Length, and equal to or smaller than the Outside Holder Length. When a new tool is created, the default value of the Arbor Diameter is equal to that of the Diameter value. The default value of the Shoulder Length is equal to that of the Cutting Length. Outside Holder Length Cutting Length Arbor Diameter Diameter Total length Shoulder Length
  57. 57. 58 Bull nose mill3.1.2 A tool of this type is defined by the parameters shown in the image. The Corner radius of the Bull nose mill tool should be in the range from 0 to half the Diameter value. The cylindrical tool arbor is added to the tool definition, same as for the End mill tool. Ball nose mill3.1.3 A tool of this type is defined by the parameters shown in the image. The Corner radius of a tool of the Bull nose mill type is equal to half the Diameter value and cannot be changed. The cylindrical tool arbor is added to the tool definition, same as for the End mill tool.

  58. 58. 3. Tools 59 Tools conversion3.1.4 InventorCAM automatically converts tools of the End/Rough Mill type created with previous InventorCAM versions into one of the three tool types described above. The tools conversion is performed according to the Corner radius value: • Tools with zero Corner radius are converted into End mill tool type. • Tools with Corner radius equal to half the Diameter are converted into Ball nose mill type. • Tools with Corner radius in the range from 0 to half the Diameter value are converted into Bull nose mill type. When an existing tool created in a previous InventorCAM version is converted into End mill/Bull nose mill/Ball nose mill tool, the value of the Arbor Diameter is defined as equal to that of the Diameter. The value of the Shoulder Length is defined as equal to that of the Cutting Length.
  59. 59. 60 Drill tool3.2 The cylindrical tool arbor is added to the tool definition. The arbor diameter and length are defined by: Arbor Diameter and (Total Length - Shoulder Length).

  66. 66. 3. Tools 67 In previous InventorCAM releases the flutes were considered to be only on the conical face (flutes length and cone length were defined by the Cutting Length value). In InventorCAM2008 R12, the cone length and flutes length are defined by separate parameters. The Cone Length is determined by the Diameter, Taper angle and Tip diameter parameters. The Cutting Length parameter defines the length of flutes. The flutes can be located at the conical and cylindrical faces of the tool. You select one of the check boxes at the side of the Tip Diameter and Cone Length edit boxes in order to define the taper tool using either the Tip diameter or the Cone Length. When the Tip Diameter check box is selected, the Cone Length check box is unselected and the relevant edit box is disabled; the Cone Length value is thus automatically calculated. When the Cone Length check box is selected, the Tip Diameter check box is unselected and the relevant edit box is disabled; the Tip Diameter value is thus automatically calculated.
  67. 67. 68 Note that the Tip Diameter is the diameter of the virtual intersection of the conical shape with the bottom plane. Parameter limitations • Tip diameter must be smaller than Diameter. • Angle must be greater than 0° and smaller than 180°. • Corner Radius must be equal to or smaller than half the Tip Diameter. • Corner Radius must be smaller than Cone Length. • Cutting Length must be equal to or smaller than Shoulder Length. • Shoulder Length must be equal to or smaller than Outside Holder Length. • Outside Holder Length must be equal to or smaller than Total Length.

  77. 77. 78 Choosing the tool type3.17 The process of the tool type definition in InventorCAM2008 R12 is as follows: when you start a new tool definition, InventorCAM displays the Tool Type dialog box in order to choose the tool type. For an existing tool, the tool type can be changed using the Change Tool type command from the right-click menu as shown.
  78. 78. 3. Tools 79 Tool Units3.18 In previous InventorCAM versions, the tools in the tool library were saved without the units data. When a tool was loaded into a CAM-Part, its dimensions were interpreted according to the CAM-Part units; therefore it was impossible to use tools with different units than the units of the CAM-Part. InventorCAM2008 R12 provides you with the possibility to assign units data to each tool in the tool library. The tool library can store tools with different units. Such functionality enables you to use tools defined in different units than the units of the CAM-Part without converting the tool parameters into the CAM-Part units. You can choose the units for the tool diameter values and tool lengths separately. The Mm/Inch radio buttons are also added to the Default Tool data page. These radio- buttons enable you to define the units used for the speed/feed definition. In the Part Tool Table, these radio-buttons are disabled; the units of the CAM-Part are used.
  79. 79. 80 When a tool library created in a previous InventorCAM version is loaded in InventorCAM2008 R12, the Assign Units dialog box enables you to assign units for tools.
  80. 80. 3. Tools 81 Angular dimensions3.19 In InventorCAM2008 R12, the button is added to each angular dimension edit box. When the button is clicked, the angle is displayed in the degrees/minutes/seconds format. The edit box becomes disabled. When the button is clicked again, the edit box becomes enabled with the angle value in the decimal format.
  81. 81. 82 Rough tools3.20 In previous versions, InventorCAM provided you with a separate tool type to define rough end mill tools. InventorCAM2008 R12 enables you to define rough tools of all the following types: • End mill • Bull nose mill • Ball nose mill • Face mill • Taper mill • Slot mill • Drill • Bore • Dove tail mill The Rough check box is added to the Tool topology page for the tools of types listed above; this check box enables you to mark the tool as suitable for rough milling.
  82. 82. 3. Tools 83 The Rough tools only and Do not display rough tools options are added to the Range dialog box. These options enable you to handle rough tools during the tools sorting. The Rough tools only option enables you to display only rough tools in the tools list. When the Do not display rough tools option is activated, the tools marked as Rough are not displayed.
  83. 83. 84 Link to the Carmex and Vardex thread milling tool libraries3.21 InventorCAM2008 R12 provides you with a link to the Carmex (www.carmex.com) and Vardex (www.vardex.com) thread milling tool libraries. This link enables you to choose the appropriate thread milling tool from the Carmex or Vardex library and import it for use inside the InventorCAM Thread Mill Operation. The installations of the Carmex (Carmex_Setup.msi) and Vardex (VardexTMGen11.0.26-Full.exe) tool libraries are located in the /Util folder under the InventorCAM installation directory. To import a tool from the Carmex or Vardex thread milling tools library, choose the Carmex or Vardex item from the standard tables list for Thread Mill and Taper Thread Mill tools. The Carmex or Vardex tool library wizard is launched. The wizard guides you through the steps to define the parameters of the tool you are looking for, selects a number of tools from the library that fit these parameters and enables you to choose one of these tools. When the tool is chosen, it is imported into the InventorCAM tool library.

If you want to edit the depth-change points defined automatically with the Profile 3D option, choose the Define depth option and click on the Pick button. The depth-change points are displayed on the model. The Define depth dialog box displays the data of these points and enables you to edit the profile depth definition by picking points manually on the model. Delta Z
  87. 87. 88 Contour 3D operation4.2 InventorCAM2008 R12 provides you with the new Contour 3D operation that enables you to utilize the power of the 3D Engraving technology for the 3D contour machining. In this operation InventorCAM enables you to prevent the gouging between the tool and the 3D contour. The Contour 3D operation performs the machining of the defined 3D contour geometry using the following technological parameters: Tool reference This option enables you to define the point on the tool which is in contact with the machined 3D contour. • Tip. With this option, the tool tip is in contact with the 3D contour; InventorCAM prevents the gouging between the tool and the 3D contour. Note that the tool axis always crosses the geometry.
  88. 88. 89 4. Milling • Center. With this option, the tool center is in contact with the 3D contour. In this case, InventorCAM does not check the gouging between the tool and the contour. Technology When the Tip option is chosen for the Tool Reference definition, InventorCAM provides you with the following technological parameters: Type This option enables you to perform the semi-finish and/or finish of the 3D contour. • Semi-finish performs the machining of the 3D contour in several steps along the Z-axis. The vertical distance between two steps is defined by the Step down parameter. • Finish will machine the 3D contour to its final dimensions in one step down. • Both is used to machine the 3D contour first with a semi-finish cut and then with a finish cut.
  89. 89. 90 Step down This value defines the vertical distance between two successive steps during the Semi-finish machining of the 3D contour. • From Upper level. With this option, InventorCAM performs a number of horizontal semi-finish passes at each down step, from the Upper Level to the defined Contour depth. • From surface. InventorCAM performs a number of 3D semi-finish passes at each step down, from the chosen 3D contour to the defined Contour depth.

  90. 90. 91 4. Milling T-Slot operation4.3 InventorCAM2008 R12 provides you with a new type of Milling operation that enables you to machine slots in vertical walls with a slot mill tool. The definition of the T-Slot Operation is mainly similar to the regular Profile operation, except for a number of parameters related to the milling of the ceiling face of the slot. Second offset number4.3.1 At the stage of the tool data definition, a new parameter related to the tool offset is available. The Second offset number parameter defines the register number of the upper cutting face offset, in the offset table of the CNC-machine. This option enables InventorCAM to automatically take into account the minor size differences between the defined tool and the one actually used for cutting the workpiece, if there are any.
  91. 91. 92 Technological parameters4.3.2 Ceiling offset For rough machining of the slot, you can define the offset for the ceiling as well as for the walls and the floor. You may choose to remove this offset with the finish pass by selecting the Ceiling check box in the Finish section. Cutting depth overlap This parameter defines the overlap of each two adjacent tool paths, in both the rough and finish machining of the slot. Ceiling offset Cutting depth overlap Cutting depth overlap
  92. 92. 93 4. Milling Cutting direction For both rough and finish cuts, you may define the direction of machining. The slot can be milled from top to bottom, from bottom to top, from middle to bottom or from middle to top.
  93. 93. 94 Face Milling Operation4.4 In previous InventorCAM versions, face milling (the machining of large flat surfaces with face mill tools) was performed by utilizing the Clear strategy of the Pocket Operation. InventorCAM2008R12 provides you with a new Face Milling Operation that includes the functionality of the Clear strategy and new advanced functionality. To create a new Face Milling operation, choose the Face command from the Add operation submenu. The Face Milling operation dialog box is displayed.
  94. 94. 95 4. Milling Geometry definition InventorCAM enables you to define the geometry for the Face Milling operation with the Face Milling Geometry dialog box. Name This edit box enables you to define the geometry name. Base Geometry This section enables you to choose the method of the Face Milling geometry definition. • Model. With this option, a rectangle located at the XY-plane and surrounding the Target model is generated and chosen for the Face Milling geometry. The rectangle chain is displayed in the Chain List section. Face Milling Geometry
  95. 95. 96 • Faces. This option enables you to define the Face Milling geometry by face selection. The Define button and related combo-box enable you either to define a new faces geometry with the Select Faces dialog box or to choose an already defined geometry from the list. When the model faces are selected, InventorCAM generates a number of chains surrounding the selected faces. These chains are displayed in the Chain List section. • Profile. This option enables you to define the Face Milling geometry by a profile. The Define button and the related combo-box enable you to define a new profile geometry using the Geometry Edit dialog box or to choose an already defined geometry from the list. The defined chains are displayed in the Chain List section. Face Milling Geometry Selected faces Face Milling Geometry
  96. 96. 97 4. Milling Chain List This section displays all the chains chosen for the Face Milling geometry. The Merge button enables you to merge all the Face Milling geometry chains into a single chain. The Separate button enables you to divide a merged chain into its initial separate chains. Modify This section enables you to offset the chain currently selected in the Chain List section. The Apply to all button enables you to apply the specified offset value to all the chains. Separate chains Merged chain Offset
  97. 97. 98 The definition of the Face Milling Operation is mainly similar to the regular Pocket operation, except for a number of parameters related to face milling. The Technology page of the Face Milling Operation dialog box provides you with the following parameters: Technology InventorCAM enables you to choose the following technologies for the face milling: • Hatch The machining is performed in a linear pattern. The Data button displays the Hatch Data dialog box that enables you to define the hatch parameters. The Hatch parameters used for the Face milling are similar to the parameters used for the Hatch strategy of the regular Pocket operation.
  98. 98. 99 4. Milling During face milling the tool path is extended over the edges of the machined face. The Extension section enables you to define the extension both along the tool path (the Along section) and across the tool path (the Across section). The extension can be defined either by percentage of the tool diameter (the % of tool diameter option) or by a value (the Value option). • Contour The machining is performed in a number of equidistant contours. The Data button displays the Contour Parameters dialog box which enables you to define the contour parameters in the same manner as for the Contour strategy of the Pocket operation. The Contour parameters used for Face milling are similar to the parameters used for the Contour strategy of the regular Pocket operation. Extension along the tool path Extension across the tool path
  99. 99. 100 Similar to the Hatch strategy, the Contour tool path can also be extended over the machined face edges. The Extension section enables you to define the extension of the tool path, same all around. The extension can be defined either by percentage of the tool diameter (the % of tool diameter option) or by value (the Value option). • One Pass With this option, InventorCAM performs the face milling in one pass. The direction and location of the pass is calculated automatically, taking into account the face geometry, in order to generate an optimal tool movement with the tool covering the whole of the geometry. The Data button displays the One Pass data dialog box which enables you to define the machining parameters. Extension
  100. 100. 101 4. Milling The Extension section enables you to define the tool path extension over the face edges. The extension can be defined either by percentage of the tool diameter (the % of tool diameter option) or by value (the Value option). The Overlap section enables you define the tool overlapping between two successive passes. This section is enabled for Hatch and Contour strategies only. Offsets The Offsets section enables you to define the value of the Floor offset, the machining allowance that is left unmachined on the face during the rough machining. The Finish check box enables you to remove the remaining offset with the last cut (if the check box is selected) or leave the offset unmachined for further operations (if the check box is not selected). Sort cut order The Complete Z-level option enables you to define the order of the machining Z-levels, in case more than one face is machined. The behavior of this option is similar to its behavior in the Pocket Operation. Extension
  101. 101. 102 Vertical zigzag passes in Profile operation4.5 In previous InventorCAM versions the linking of the profile machining passes located at successive Z-levels (defined with the Step down parameter) was performed by rapid movement up to, at and down from the Clearance level. At the end of each pass the tool performed a retreat movement to the operation Clearance level, a horizontal movement at rapid feed to the beginning point of the next pass and then descended to the Z-level of the next pass. With this method InventorCAM kept the same cutting direction (either climb or conventional) along the whole tool path. InventorCAM2008 R12 provides you with the possibility to connect the passes located at two successive Z-levels directly from the end of a pass to the beginning of the next pass. With this connection method, the machining is performed in a zigzag manner; the machining changes to the opposite direction from one pass to the next. The Depth cutting type section is located in the Technology page of the Profile operation dialog box. This section enables you to switch between the One way and Zigzag options. When the One way option is chosen, the cutting passes are oriented in the same direction and connection between them is performed through the operation Clearance level. When the Zigzag option is chosen, the tool path is performed in a zigzag manner, with the tool path direction changing from one pass to the next. The Zigzag option cannot be used together with the Clear offset technology.
  102. 102. 103 4. Milling Lead in and Lead out When the Lead in/out strategies are used together with the Zigzag option, InventorCAM calculates the lead in/out movements for all the cuts according to the direction of the first cutting pass, irrespective of the direction of the other cutting passes. During the tool path linking, InventorCAM connects the cuts (containing lead in and lead out movements) in a zigzag manner and changes the direction of all even cuts to the opposite. Therefore only for odd cuts, the Lead in strategy is used for the lead in and the Lead out strategy is used for the lead out. For even cuts the Lead in strategy is used for the lead out and the Lead out strategy is used for the lead in. Tool side and compensation When the Zigzag option is used, the Tool side combo-box defines the tool location for the first cut. For each successive cutting pass, the tool position relative to the geometry direction is changed. When the compensation is used for the tool path linked using the Zigzag option, InventorCAM takes into account the machining direction and the changes in the tool position relative to the geometry direction for each successive cut. The different compensation commands are used in the GCode output for even and odd cuts. Movements defined by Lead in strategy Movements defined by Lead out strategy
  103. 103. 104 Equal step down in Profile and Pocket operations4.6 In previous InventorCAM versions, the machining of the Profile and Pocket operations started from the Upper level and continued on a number of successive Z-levels till the operation Depth (modified with the Floor offset and Delta depth parameters). The distance between two successive Z-levels was determined by the Step down parameter. If the machining depth was not divisible exactly by the Step down parameter, the depth of the last cut was smaller than the Step down parameter. InventorCAM2008 R12 provides you with the Equal step down option that enables you to keep an equal distance between all Z-levels. With this option you have to specify the Max. Step down parameter (instead of the Step down parameter). For Profile operations, the Equal step down option is added to the Technology page of the operation dialog box. Step down Last cut depth
  104. 104. 105 4. Milling For Pocket operations, it is added to the Levels page of the operation dialog box. According to the operation Depth (modified with the Floor offset and Delta depth parameters), InventorCAM automatically calculates the actual step down to keep an equal distance between all passes, while making sure not to exceed the specified Max. Step down value. Max. Step down Actual step down
  105. 105. 106 Final cuts machining in Profile and Pocket operations4.7 InventorCAM2008 R12 provides you with the option to divide the depth to be machined into two regions, each with its own Step down, with the second region, close to the depth bottom, having the smaller Down step. For Profile operations, the Final cuts button is added to the Technology page of the operation dialog box. For Pocket operations, it is added to the Levels page of the operation dialog box. This button displays the Final cuts dialog box. This dialog box enables you to define the parameters of the Final cuts machining.
  106. 106. 107 4. Milling When the Final cuts used check box is activated, the option is used. The Number of steps parameter defines the number of Final cuts. The Step down value defines the distance between two successive Final cuts. When the Final cuts option is used, the check box on the Final cuts button is selected. When the Final cuts option is activated, InventorCAM performs the machining with the operation Step down from the Upper level till the depth calculated according to the following formula: Depth - Number of cuts * Step down. From this depth, the machining is performed in a number of cuts determined by the Number of cuts/Step down parameters in the Final cuts dialog box. The machining is performed in such manner till the full operation depth. Step down Final Cuts Step value
  107. 107. 108 Wall Draft angle in Profile and Pocket operations4.8 In previous InventorCAM versions, it was possible to perform Profile and Pocket operations on vertical walls only. InventorCAM2008 R12 enables you to perform the machining of walls inclined with a constant draft angle along all the geometry. The Wall draft angle button is added to the Technology page of the Profile and Pocket operation dialog boxes. This button displays the Wall draft angle dialog box. When the Wall draft angle check box is activated in the dialog box, the inclined wall machining is performed. The External wall angle parameter defines the draft angle of the wall; the angle is measured from the Z-axis direction as shown. The Islands wall angle parameter defines the draft angle of the island walls. This parameter is relevant only within the Pocket operation; the angle is measured similar to the External wall angle parameter.
  108. 108. 109 4. Milling For the inclined wall machining, each cutting pass located at a specific Z-level is generated according to the specified External/Island wall angle parameter. The External corner type option enables you to define how the cutting passes will be connected during the external corners machining. The following possibilities are available for two possible types of corners in the geometry model: If the geometry model has sharp corner there are two options for creating tool path at the corner: • Sharp Corner. With this option the tool path is calculated so as to perform the machining of a sharp corner. • Conical fillet. With this option the tool path is calculated so as to perform the machining of the corner with a conical fillet; the radius of the tool path rounding increases from one pass to the next. If the geometry model has filleted corner there is one option for creating tool path at the corner: • Cylindrical fillet. The tool path is calculated in such a way so as to perform the machining of the corner with a cylindrical fillet; the radius of the tool path rounding is the same for all the cutting passes. Geometry Geometry Geometry
  109. 109. 110 Profile floor machining4.9 In previous InventorCAM versions, the Profile operation enabled you to define a machining allowance in the XY direction (Wall offset), leaving it unmachined during the profile roughing and removing it during the finishing passes (in the same operation or in another Profile operation). InventorCAM2008 R12 provides you with the possibility to define a similar allowance in the Z-direction (Floor offset). This Floor offset is left unmachined during the profile roughing and removed during the finishing. The Floor offset parameter is added to the Offsets section, located on the Technology page of the Profile operation dialog box. The Floor offset parameter is available only when the Rough section is activated. When the Floor offset is specified, InventorCAM performs the machining by the Z-levels defined with the Step down parameter. The machining is performed up to the Floor offset from the Profile depth. The Clear offset section enables you to define the parameters of the Clear offset machining for the roughing and finishing passes. Floor offset Step Down Profile Depth
  110. 110. 111 4. Milling The use of the Clear offset option for the Profile finishing enables you to perform the machining of both the Wall and Floor offsets. In this case, InventorCAM performs first the machining of the floor area and then the walls. The floor area is machined with a single cutting pass at the Profile depth. This cutting pass is calculated using the Clear offset strategy (with the specified Offset and Step over parameters) and taking into account the specified Wall offset. The wall finishing is performed from the Upper level till the Profile Depth in a number of steps defined with the Step down parameter. Offset Wall offset Step Over Step Down Profile Depth
  111. 111. 112 Pocket Wall finishing4.10 In previous InventorCAM versions, the pocket walls finishing was performed with a single cut at the whole Pocket depth. InventorCAM2008 R12 enables you also to perform the finishing of the walls in a number of successive cuts, with the distance between them defined by the Step down parameter. The Depth section is added to the Finish section of the Pocket operation dialog box. This section enables you to choose how the wall finish will be performed: either at the whole depth (Total depth option) or in a number of steps at each step down (Each step down option). The options of the Depth section are available only when the wall finishing is performed in the operation (the Wall or Floor option is used for the Finish). When the Wall draft angle option is used in the operation, the Depth options are disabled and the Each step down option is used for the Wall finishing. Finish passes Single Finish pass
  112. 112. 113 4. Milling 4.11 Open Pocket machining InventorCAM2008 R12 provides you with the functionality to perform the machining of a pocket with a combination of open edges and closed walls. This functionality generates optimized tool path and lead in movements. Open Pocket Geometry definition4.11.1 InventorCAM enables you to define the geometry for the Open Pocket Machining by defining open edges on the conventional Pocket geometry. The Mark open edges command is added to the right-click menu available on chain items in the Chain List section of the Geometry Edit dialog box. This command displays the Mark Open Edges dialog box. This dialog box enables you to mark the open edges on already chosen pocket chains by picking on them. The Mark as section of the dialog box enables you to choose the selection mode. When the Open option is chosen, picking a pocket geometry edge marks it as open. When the Wall option is chosen, picking a pocket geometry edge marks it as closed (wall). With the Toggle option, picking a closed edge marks it as open and vise versa. Open Pocket Pocket geometry Open edge Closed edges
  113. 113. 114 The Select section enables you to choose the selection method. When the Single entity option is chosen, InventorCAM enables you to pick single entities in order to mark them in order to mark them as open/closed. When the From/To entities option is chosen, InventorCAM enables you to mark a segment of the pocket geometry by picking the start and the end entities. The CAD Selection button enables you to perform the selection using the CAD tools. Open Pocket machining parameters4.11.2 The Open Pockets section is added to the Technology page of the Pocket operation dialog box. This section is enabled only when the pocket geometry contains open edges. During the Open Pocket machining the tool path is extended beyond the open edges. The Extension section enables you to define the overlapping between the tool and the open edges; the overlapping can be defined either by percentage of the tool diameter (the % of tool diameter option) or by value (the Value option). TheUse profile strategy optionenablesyoutoperform the Open pocket machining in a Profile manner. The tool path at a specific Z-level consists of a number of equidistant profiles starting from outside the model (at the distance defined by the Extension parameter). The tool moves in parallel offsets to the pocket geometry. Extension Open edge
  114. 114. 115 4. Milling The One way/Zigzag options enable you to define the tool path direction and linking. • With the Zigzag option, the tool finishes one profile pass and then directly moves to the next pass. The machining is performed without leaving the material, thus constantly switching between climb and conventional milling. • With the One way option, the tool finishes one profile pass, then rapidly moves (G0) to the safety distance and then to the start of the next cutting pass. The cutting direction (either climb or conventional) is preserved for each cutting pass. The Approach from outside option enables the tool to approach from outside of the material in the open pocket areas, if possible. Such an approach enables you to decrease the tool loading when plunging into the material. This option enables InventorCAM to perform the approach movement from an automatically calculated point outside of the material. The tool moves to the necessary depth outside of the material and then plunges into the material. The Descend to cutting level with Rapid option enables you to avoid vertical non- machining movements outside of the material performed with the working feed by direct rapid movement down to the cutting level.
  115. 115. 116 When this check box is selected, the tool descends from the Clearance level outside of the material directly to the cutting level (defined with the Step down parameter) using the Rapid feed. Then the horizontal movement into the material is started with the working feed. When this check box is not selected, the tool descends from the Clearance level down to the Safety distance with Rapid movement. From the Safety distance, the tool descends down to the cutting level (defined by the Step down value) with the defined feed and starts the horizontal cutting movements into the material with the working feed. The Descend to cutting level with Rapid check box is available only when the Approach from outside check box is selected. Upper level Safety distance Cutting level Rapid movement Feed movement Upper level Cutting level Rapid movement
