General and flexible methodology and architecture for CAPP: GF-CAPP system

subject

description

Although all researchers insist on the need to develop computer-aided process planning (CAPP) systems, they agree that one of its most significant shortfalls is the low level of generality and flexibility present in current proposals. One of the outcomes of this low level of generality--apart from its limited application domain--is the low level of integration achieved with CAD, CAM and PP&C systems. To ensure optimized running of the production system, it is also important to stress the need to develop alternative process planning that enables it to adapt to disruptions in production. Several factors play an important role in implementing these features, among which the following may be highlighted: the planning methodology, the system architecture and the information models used to store data and knowledge. This paper proposes a methodology and architecture suitable for generating the process plan of machining parts. It is a proposal in which the peripheral processes needed for these parts are taken int...
