  3. 3. Nesting - Getting Started Guide Nesting Getting Started Guide Welcome to the Getting Started Guide for Nesting. Nesting refers to the process of efficiently manufacturing parts from flat raw material. In order to minimize the amount of scrap raw material produced by this process, companies use nesting software. The software analyzes the parts (shapes) to be produced at a particular time. Nesting is an add-on module for RhinoCAM 2012 that can efficiently arrange parts within sheet material by considering either the part's true shape or its rectangular form. This product offers a simple and easy to use wizard driven interface to nest parts and make them ready for CAM programming with RhinoCAM. What are Sheets and Parts? Part(s) refers to shapes to be produced that are cut from a flat piece of raw material. The raw material to be cut from is called Sheet(s). These sheets could be rectangular or any arbitrary shape. Parts and sheets can be created using CAD tools in Rhinoceros or can be imported as Dxf, Dwg, Rhino, IGES. About this Guide This document contains various tutorials to help you get started with learning Nesting. Each tutorial lesson has two associated files that you can find located in the Tutorials folder under the installation folder of RhinoCAM. The first file is a completed file that contains the nested results and represents the file that you should end up with after working through the tutorial. The other file is a starter file that contains only the geometry. Use the completed file as a reference. Copy the starter file and use this file to begin each tutorial. Good luck and have fun! Where to go for more help? Refer to the online help system for nesting. This can be located by selecting Help from the Nesting browser. If you need additional help, or if you have any questions regarding Nesting, you may contact us via e-mail at support@mecsoft.com. MecSoft offers Online training as well as personalized full day training sessions. Please look up our website or email us at sales@mecsoft.com for further details. © 1997-2012, MecSoft Corporation 3
  4. 4. Nesting - Getting Started Guide Tutorial 1: True Shape Nesting © 1997-2012, MecSoft Corporation 4
  5. 5. Nesting - Getting Started Guide Introduction This tutorial will illustrate nesting of parts of arbitrary shapes to a rectangular sheet using true shape nesting. This method is useful when the actual geometric details of the part are taken into consideration while nesting. No approximation as a rectangle or any other simpler shapes is made while nesting parts on the sheet. True shape nesting enables interlocking of parts and holes present in the part. In this tutorial we have a total of 4 shapes (parts) to nest of which one of them contains 2 holes. The parts will be nested to 2 sheets of same size each being 24 x 12 inches. Open RhinoCAM Nesting is an add-on module for RhinoCAM. To open RhinoCAM select the Rhinoceros shortcut on your desktop or from the program menu by selecting Start ->All Programs >Rhinoceros 4.0 ->Rhinoceros 4.0.exe. Load Nesting Browser From the drop down menu bar select RhinoCAM ->Nesting Browser Nesting Browser is now loaded and by default appears to the left of view port. © 1997-2012, MecSoft Corporation 5

The file is now loaded and appears as shown below. © 1997-2012, MecSoft Corporation 6
  7. 7. Nesting - Getting Started Guide Nesting Browser Workflow Nesting browser uses a 5 step process to create 2D nesting of parts.      Select Type of Nesting Select Sheet(s) to Nest Parts in Select Part(s) to Nest Choose Nesting Parameters Preview and Commit Nest Select Type of Nesting This tab allows the user to choose between True Shape Nesting and Rectangular Nesting. In this tutorial we will use True Shape Nesting. 3. From Select Type of Nesting tab click the radio button next to True Shape Nesting. © 1997-2012, MecSoft Corporation 7
  8. 8. Nesting - Getting Started Guide This method is useful when the actual geometric details of the part are taken into consideration while nesting. No approximation as a rectangle or any other simpler shapes is made while nesting parts on the sheet. True shape nesting enables interlocking of parts, recognition of arbitrary shaped sheet and part geometries, and holes present in the sheet and part. Select Sheet(s) to Nest Parts in This tab allows selection of sheet(s) to nest parts. 1. Switch to Select Sheet(s) to Nest Parts in tab. We will now select the 24 x 12 in rectangle as the sheet. 2. Click the Select Curve(s) button. Clicking this button prompts you to “select objects and hit right mouse to end” selection. You could also press enter on your keyboard to end selection. © 1997-2012, MecSoft Corporation 8
  9. 9. Nesting - Getting Started Guide 3. Now select the rectangle from the view port (graphics area) 4. Press enter to end selection. The selected geometry now turns blue color and appears under the Select Sheet(s) to Nest Parts in tab. © 1997-2012, MecSoft Corporation 9
  10. 10. Nesting - Getting Started Guide 5. You will now set the sheet parameters. a. Set Count = 2 by entering the value in the cell for count. b. Select Starting Corner as Lower Left c. Nesting Direction as Along X d. Grain Direction as None     Setting Count = 2 will nest the parts to 2 sheets of same size. Starting Corner defines the corner of the sheet to start the parts to nest within a sheet. Nesting Direction defines the direction along which the sheet gets filled with parts. Grain Direction can be used to control the part's orientation on the sheet so that any material grain is considered. Each part and sheet needs to have this parameter set for the control to be useful. Select Part(s) to Nest © 1997-2012, MecSoft Corporation 10
  11. 11. Nesting - Getting Started Guide This tab allows selection of Part(s) to be nested. 6. Switch to Select Part(s) to Nest tab. We will now select all shapes. Note: Part #4 is made up of 3 curves. These would be listed as separate entries when selected in the table of parts to nest. Nesting treats shapes that are topographically defined within other shapes as cutouts, meaning treat the part periphery shape and cutout shape(s) as a group. 7. Click Select Curve(s) button under the Part(s) to Nest tab. Clicking this button prompts the user to “select objects and hit right mouse to end” selection. You could also press enter on your keyboard to end selection. © 1997-2012, MecSoft Corporation 11
  12. 12. Nesting - Getting Started Guide 8.

Press enter to end selection. The selected geometry now turns red and appears under Parts tab. A white dot on each curve indicates the start point for profile machining. 10. You will now set the part parameters. a. Set Count = 10 for Part1, b. Count = 25 for Part2, c. Count = 15 for Part3, d. Count = 18 for Part4, Part5 and Part6 e. Leave Orientation as unchecked and Grain Direction as None for all Parts © 1997-2012, MecSoft Corporation 12
  13. 13. Nesting - Getting Started Guide As Parts 4, 5, and 6 are shapes that constitute one part, you would set Count as 18 for each of those shapes to achieve 18 copies of the part. Nesting treats shapes that are topographically defined within other shapes as cutouts, meaning treat the part periphery shape and cutout shape(s) as a group. 11. You will now set the part options before defining the nesting parameters. This is located under Set Part(s) to Nest tab below select curves to be used as parts. a. Set Orientation Step Angle = 45 b. Select check box for Allow Part inside other parts   Setting the Orientation Step Angle to 45 allows rotation of parts at 45 degree increments. Selecting Allow Part inside other parts maximizes sheet utilization. Choose Nesting Parameters 12. Switch to Choose Nesting Parameters tab © 1997-2012, MecSoft Corporation 13
  14. 14. Nesting - Getting Started Guide You will now specify the minimum distance between adjacent parts, the minimum distance between parts and the sheet edge and the nesting accuracy. 13. Set Distance Part to Part = 0.25 14. Distance Part to Sheet = 0.5 15. Accuracy to High Define each of the three options above as was done with the previous options.  Distance Part to Part is the minimum distance allowed between adjacent parts in the nest.  Distance Part to Sheet is the minimum distance allowed between parts and the edge of the Sheet(s).  Accuracy defines the degree of accuracy of nested pattern 16. Now click Execute Nest. This computes nest based on sheet, parts and nesting parameters specified. Once the nest is computed, you can select the preview nest button to view the nested results in the graphics area. 17. Select Preview Nest. © 1997-2012, MecSoft Corporation 14
