Knowledge Based Integrating Modeling Method for Stamping Product and Process

Based on the development of current intelligent design technology, the knowledge based modeling method, which integrates stamping product and process in progressive die, was put forward. The integrating knowledge model for stamping part was constructed and its key technologies were analyzed. The method of feature based modeling facing to process planning was researched, and the mechanism, which integrates the single feature definition, the stamping process analysis model and process rule, was established. The knowledge integrating strategy for the strip layout was analyzed, and the design method to integrate the general case model for the strip layout and the analysis model between steps was proposes. The ways to deal with the geometry in integrating knowledge model was summarized, and the principles to treat the geometry based on CAD platform was put forward. The results show that the design ability of stamping process can be improved effectively by using the integrated knowledge model.
