Drawing Process Design Based on Fuzzy Knowledge Reasoning

As well known, stamping process design involves lots of empirical knowledge, which prolongs the cycle of design and manufacturing and limits the competitiveness of the enterprises. With the development of computer technologies, CAD/CAM/CAE technologies have been widely applied to the design of the stamping processes and dies, but it still needs a large number of engineers' experiences. In this paper, the process of traditional stamping process design using fuzzy theory was presented, and a drawing process design system was established, which mainly includes input and output module, knowledge data-base module, process design module. And then, the intelligent adjustment model of design process that provided by fuzzy theory converting knowledge data-base to non-linear mapping was established. Finally, a typical part was taken as an example to demonstrate the running process of the system; the result showed that the system is effective.
