Form GCDs

Extracted GCDs include three types of Form GCD (which differ with regard to the Sub Type property):

• EMBOSS: these are created by the Stretch Form process. If there is more than one EMBOSS form, one is chosen as the primary form and is assigned to the Stretch Forming operation; all other forms are assumed to be created by this operation as well, though they are not explicitly assigned to it.

• CURVED_BEND: these GCDs are assumed to be hand formed. They are created by the Bench Operation process, and assigned to the Manual Forming operation.

• STAMP: on Stretch Forming parts, these represent areas of thickness reduction that are assigned to chemical milling, when the Chemical Milling process routing is manually selected.
