ABSTRACT

This paper evaluates the feasibility of using parametric programming in the implementation of feature-based machining. Custom Macro B was used in this study. Macro programming technique comprises of a main program and subprograms. NC program for a basic type of machining feature namely pocket was first generated using macro and CAM system. Macro program utilizes very fewer blocks than CAM generated program. The different between both programming methods are discussed. Finally, an integrated feature based machining system is proposed.
