Product Rapid Design And CAPP Integration For Middle And Small Enterprises

The key technologies, system architecture and realization methods of rapid design and integration of CAD/CAPP are studied in this paper for the requirement of the middle or small factory. Then, taking Nanjing Chencan mechanical factory as an example, Internet-based and rapid design and integration of CAD/CAPP system is developed. The main research work and achievements in the paper are as follows:On the basis of researching Automobile Group Technology, devising the coding rule system for middle and small factory by coding theory, classifying for enterprises products efficiently, and laid the groundwork for parametric design. In order to integrate CAD/CAPP, a product definition model based on feature is made in this dissertation. According to the information requirements of information integration system, feature definition and so on are all researched systematically. Then product definition model is proposed on the base of research of feature.On the base of coding system, CBR (Case-based Reasoning), Socket, Pro/Engineer and Pro/Toolkit and so on are utilized to realize customization product quickly.On the base of researching basic theory of feature modeling, realize the integration of CAPP based on Internet by using ActiveX and Second-development technology. The system architecture and realization methods are studied in this paper.On the basis of as mentioned theories previously, Internet-based internal grinder customization system is realized. Designers can join in the design process really and expediently. The system provides some functional modular including product browse, product customization, orders management, system management and so on. The model of product in the form of AUTOVUE is exhibited to customers finally.
