The previous chapter described the fundamental components of the BCAPP system. It is also essential to describe what the BCAPP system will be providing process plans to. Basically once the process domain has been chosen (e.g. machining, assembly, etc.) there are many excellent commercial and research software packages that support this function of a CAPP system. In this section the conversion of the process plan to operation details, and preparation of documentation is reviewed. An interface to one commercial system for machining operation planning, called MetCAPP, will be described, as well as the requirements for an operation planner for injection molding.
