【Abstract】 The task of process planning is to translate design data into workinstructions to produce a part or a product. With the development of computerscience and manufacturing systems, conputer aided process planning (CAPP)has become very important in manufacturing systems. The theories of artif-icial intelligence and expert system have provided powerful means for compu-ter aided process planning. The paper describes the basic concept of processplanning and basic problems about planning strategy, constraints and conflicts,ordering in computer aided process planning systems. Some practical CAPPsystems have been analysed to illustrate these problems. The existing problemshave been solved, and the prospect of CAPP is brought forward.更多还原
