Creating a Half Pierce Stamp

This task shows you how to create a half pierce stamp by specifying the punch geometrical parameters.

Open the NEWStamping4.CATPart document from the samples directory.
If you use the Aerospace SheetMetal Design workbench, open the Aero_Stamping4.CATPart document.

1. Click Circular Stamp .
   The Circular Stamp Definition dialog box is displayed.

2. Select a point on the top face.

3. A grid is displayed to help you position the circular stamp.

4. Check the Half-pierce box
   

5. Change the value in the different fields, if needed:

   In the Height H field, specify the height value for the half-pierce circular stamp. Use the icon next to the field to specify the reference from which the height is defined: or . In the Diameter D field, specify the major diameter value for the half-pierce circular stamp.
   	By default, the angle is of 90 degrees.

6. Click on Preview to display the Half Pierce Circular Stamp.

7. Click OK to validate.

   In the Specification tree Half Pierce (Circular).1 is created.
   	The Half-pierce check box is also available on the Surface Stamp Definition and the Curve Stamp Definition dialog boxes.
   	You cannot create a cutout that is to overlap the half pierce stamp. Yet, you can create a cutout on the bottom of a half pierce stamp.
