The process features and shape features of the electronic part are classified and defined, and then the feature model library is built, which enables rapid input of the part information. The rules and methods of stamping process design are summarized to build the stamping process library, so that the stamping process can be designed rapidly and intelligently. Furtherly, the process design rules and methods in process station layout of multi-station progressive die as well as the methods of decompounding and compounding process and the expression method of the process station layout are concluded and summarized, and then the rule library and case library of process station layout are built. Designing the process station layout rapidly is carried out based on rules and cases. At last the rapid design function of process station layout is validated through simulating the rapid designing layout system of multi-station progressive die on Pro/E 3D platform.
