Abstract

This paper presents the research on the development of expert design system as a 3D CAD customising systems for the draw die in automotive industry. This system support the die design efficiently and systematically by utilizing standard data, design knowledge. The standard data and design knowledge of draw die has been accumulated through interview with design experts of Motor Company in Korea. This paper describes a methodology for systematic die design, automatic checking of dimensions and how to implement it. The expert design system is being developed on the basis of product data. All components of die are regarded as product data and system takes the component as the unit of die. Parametric design using knowledge base and standard database is introduced for easily deal with various and complicated design knowledge. For implementation, this expert system is programmed by C and Motif. And system can be used linked with CATIA.
