About Punch Contour

When you create a punch tool by planning elements with Process Generator Wizard (For example when planning a stamped surface to one OP)

• A default concept geometry is associated to the punch custom geometry Punch_Contour.
• A convex polygon is created from the punch input geometries and direction: This is the first draft of a punch outline for the punch tool.
• A die and blank holder tool is created.
• A default blank holder surface is automatically associated to the blank holder tool geometry, with the following inputs:
  • The blank geometry from the process method plan.
  • The computed punch contour.
  • The offset attributes Tool_Binder_Milling_Offset and Tool_Binder_Drawbead_Offset from the blank holder tool.

The process is as follows:

• Create a fill of the blank contour.
• Project the punch contour on the fill.
• Split the fill by the punch contour.
• Create a first offset of the blank contour, using Tool_Binder_Drawbead_Offset.
• Fill the gap between the second offset and the blank contour.
• Join both fills.

The result is associated to the blank holder tool.
