Process design and representation of automobile panel stamping for information integration

To share the design data and knowledge by utilizing existed design cases, based on the representation of object-oriented case information constitution relationship, Product-Feature-Geometry structure was proposed in order to refine the case representation, multi-type properties were adopted to describe more detailed information, three hierarchies of index strategy were used to realize information extraction. Furthermore, experts knowledge and experience on previous design cases and forming problems were collected, which can provide designers useful practical experience and data to aid design procedure and solve the potential problems of automobile panel stamping. Database technology was applied to realize a prototype system of information integration-oriented case base, which can be used to integrate process design information and manufacture resources.
