This paper presents the development of a design supporting system for press die of automobile panels. The proposed system supports the design process of press die efficiently and systematically by utilizing standard data, and reflecting knowledge of press die design collected and accumulated through the interviews with design specialists working in a Korean motor company. This paper illustrates a methodology for systematic press die design, automatic checking of dimensions and implementation.In addition the rule-based design system is developed based on the product data. All components of the press die are regarded as product data and the omponents are regarded as the unit of press die. Parametric design using knowledge base and standard database is introduced to make it easier to deal with the complicated design knowledge easily. For implementation, the ule-based design system is programmed with C++ and Motif and the system can be linked with CATIA. 1 Introduction Reducing manufacturing cycle time is an important issue in the recent automobile industry with changing customer needs. Although the industry has adopted various new technologies such as CAD/CAM and factory automation, the results do not meet the expected level. The main reason is that the new technologies must be adapted to the industry’s own know-how and knowledge workflow, as well as administrative traits of a particular company. [1] In designing and manufacturing of trim die and draw die, the variety of c
