Integration of the CAD/CAPP/PPC systems

The necessary condition that must be performed in order to ensure full functional integration of the computer aiding systems of technical and organizational production preparation is utilisation of the coherent product model. Utilisation of feature method for representations of the construction and the technological process elements is a key factor for integration of design and technological process planning—CAD/CAPP integration model. The availability of alternative process plans plays the main role in the CAPP/PPC system integration. The main advantage of the accessibility of alternative process plans for product is that we may fast react on a disturbance in the course of the manufacturing process by help of the reactions knowledgebase—one of the module of proposed PPC system. This paper describes a methodology for integration CAD/CAPP/PPC systems in detail.
