A method of CAx information integration of punched sheet metal parts on STEP based model in concurrent engineering environment

摘要

CAx information integration, which is based on the standard of STEP, is an extremely important key technology in the field of concurrent engineering research and plays significant role in promoting the development of information integration technology. This paper, in the applied setting of the project--"Concurrent engineering of product development of freight cars in Qi-Qi-Ha-Er Vehicle Plant", has made research on the information integration methods of punched sheet metal parts and thereby has made constructive exploration into the application of theoretic research to engineering practice.
