ABSTRACT
This chapter presents an overview of the research work in computer-aided process planning (CAPP) during the past 2 decades. This has been driven primarily by the need to automate the mapping of design information and intent from computer-aided design (CAD) systems to instructions for driving automated manufacturing equipment. While the concept of CAPP extends over all manufacturing domains, we summarize those developments primarily in the machining domain. As part of CAPP research, we also discuss developments in the area of feature recognition. Features are fast becoming the mechanism through which higher level design information is embodied and manipulated within the computer-aided engineering (CAE) environment. Feature recognition is one mechanism by which this higher level of abstraction is constructed and related to the underlying geometry. Finally, we briefly introduce a new area of research in CAPP, parallel machining.
