Published on

This session communicates the fundamentals of a sheet metal model in Solid Edge. ST4 made it easier to traverse between sheet metal and part, ST5 takes it a step further and removes the boundaries altogether allowing the creation of sheet metal parts in part documents. Attendees will learn the common concepts of sheet metal modeling while also exploring ways to create sheet metal parts in part documents. Workflows including, sheet metal in part - Part in sheet metal, designing and editing sheet metal bodies in Part, designing and editing from assemblies, and when to use Ordered vs. Synchronous features.

  7. 7. Defining Bend Properties Bend Radius Demo  Application- >Properties->Material Table->Bend Radius  Tools->Variables->BendRadius Bend Relief  Application- >Properties->Material Table->Relief<Width/Depth>  Tools->Variables-> Relief<Width/Depth> © Siemens AG 2012.

  8. 8. Creating Sheetmetal in Part (ST5) Creating Sheetmetal parts in Part documents Demo  Typical usage  Change in design intent i.e., starts as regular part but it needs to be a Sheetmetal part now  Translated parts  ST5  Commands  Switch to Sheetmetal – Enabled in ST5  Add Body feature – New in ST5  Behaviour  Document type is unchanged i.e., still a Part document  Sheetmetal properties added to the Part document  Sheetmetal environment activated  Sheetmetal parts can be created and edited like in native Sheetmetal documents © Siemens AG 2012.

  9. 9. Overriding Sheetmetal Properties (Ordered) Bend parameters (Radius and Bend relief) can be overridden locally Demo  Feature->Options © Siemens AG 2012. All Rights Reserved.Page 9 Siemens PLM Software
  10. 10. Overriding Sheetmetal Properties (Sync) Bend parameters (Radius and Bend relief) can be overridden locally Demo  Bend->Bend Handle->Options © Siemens AG 2012. All Rights Reserved.Page 10 Siemens PLM Software
  11. 11. Bending Demo  Bending causes the inside surface to be compressed and outside to be stretched.  In practice what this means is that using the bend arc length on either layer face for determining the flat length will be incorrect.  Or using the plate lengths including the bends will also result in incorrect flat length -Use outer layer lengths 191.42 -Use inner layer lengths 175.71 -Use just plate lengths up to bends 200.00  Or what happens when you create a bend on a flat? © Siemens AG 2012. All Rights Reserved.Page 11 Siemens PLM Software
  12. 12. Flat lengths Computation of flat correct lengths involves accounting for the material transition during the bending process. The constants are the tab lengths either to the inside of the bend or to the outside of the bend Flat length = A + B – Bend Deduction Flat length = C + D + Bend Allowance Bend allowance (BA)  PI * (inside bend radius + neutral factor * material thickness) * bend angle/180 Bend deduction (BD) = 2 * outside set back – Bend Allowance © Siemens AG 2012. All Rights Reserved. Page 12 Siemens PLM Software
  13. 13. What is Neutral Factor (K-Factor)? Between the inside and the outside surfaces, there is a layer which is neither compressed nor stretched. This is known as the neutral layer. Neutral factor helps determine the location of the neutral layer. Neutral factor depends on bend radius, bend angle, ambient temperature, direction of material grain, bending methods etc. Neutral layer helps determine the correct length of bend. References: Wiki Article, look at the references section in the article for more details © Siemens AG 2012.

  14. 14. Defining Neutral Factor in SE Neutral Factor Demo  Application- >Properties->Material Table- >Gage Tab  “Use Excel File”  Users can use “Gagetable.xls” to define their own materials, bend radii, bend reliefs and also neutral factors for various bend radii and bend angles.  “Bend Equation group”  Users can define their own neutral factor through a VB program  Tools->Variables->Neutral Factor  Neutral factor can also be defined for each individual bend in Sync or per feature in Ordered © Siemens AG 2012.

  15. 15. Transforming regular parts to Sheetmetal Typical workflow Demo  Translated Parts  Need to flatten or change thickness  Change in requirements  Starts as Part and needs to be Sheetmetal now Feature(s)  Transform to Sync Sheetmetal (Ordered/Sync)  Transform to Sheetmetal (Ordered)  Automatically adds bends  Option to rip the model  Cut  Users can custom rip the part Note  Transform commands are enabled in Part documents from ST5  If in Part and want to work in Ordered, Transition to Ordered, Switch To Part and then run Transform to Sheetmetal command © Siemens AG 2012.

  16. 16. Etch & DXF DemoGeneral guide lines for creating text on SE models Always use Solid Edge Stencil or Stencil font Prefer Etch instead of creating a SE feature to add or remove material  Etch is lighter by nature as it does not modify the solid Translating to DXF  Application->Save->Save As Flat  By default the file type is set to DXF format  Go into Options dialog  Set the option to “Export Etch text as text box” to post process in AutoCAD the text box to stick type font  Go into Font Mapping tab on Options dialog and ensure that the stencil font is mapped to one of AutoCAD’s stick font e.g., txt.shx, monotxt.shx  Ensure that in Sesmf.ini file the following entry is present under [Write Text Fonts] – “Solid Edge Stencil=txt.shx”  AutoCAD – Converting text boxes to stick type font  Use AutoCAD command - Express ToolsModify TextExplode © Siemens AG 2012.

  17. 17. Sync Sheetmetal – Why & When? The Why? Demo  Easy creation  Easier edits  Multiple flange creation  Easy creation of straight break bends  Individual bend control  Non-orthogonal plates/tabs  Translated parts  Transform to Sync Sheetmetal command to creates native tabs and flanges  Can change thickness and bend radii values  And a lot more……. The When?  Straight break bend parts  Start with Tabs, Flanges and holes  Graduate towards Contour Flanges, Patterns, Mirror  Remember Hybrid © Siemens AG 2012. All Rights Reserved.Page 17 Siemens PLM Software
  18. 18. Ordered Sheetmetal – Why & When?  Ordered  Rolled Parts  Lofted Flange  Arcs to lines and vice-versa  Contour Flange along arcs  Unbend/Re-bend  Smart Cuts (cuts across bends)  3 bend Corners  Holes on bends  Features across bends  Creating Part features . . . © Siemens AG 2012.
