Selecting a primary process group
A process group is a group of processes of the same manufacturing type. For example, the Sheet Metal process group includes such processes as Laser Cut, Bend Brake, Shear, etc.; while a Casting process group includes Cool, Cleaning, Hot Box, Melting, etc.
Some components may be completely manufactured using processes in a single process group. Other components require multiple process groups; for example, Casting and Machining.
The name of the process group that is primarily used to manufacture a component shows on the Primary Process Group button.
