The Research Of The Key Technology On The Integration Of CAD/CAPP In Concurrent Engineering

The integration of CAD/CAM is the requirement of the development of the advanced manufacturing technology. The CAPP is the key link to CAD/CAM, and it is also the bottleneck of the development of CAD/CAM, therefore the meaning of research in CAPP is profound.In CAD/ CAM integrate system, CAPP convert the information from design to manufacture and management. It get geometry and technology information from CAD system, obtain the working conditions of enterprises , resource state and the technique level of worker from technology database, and then accord to those information format the technology process card, work step card etc..The purpose of this subject is to extract part's information from the feature build module, deal those message in CAPP system, and then create process card accord to the message saved in process database, thus realize the information convert from design to manufacture.
