Study on Process Decision Methodology for Sheet Metal Stamping by Case Based Technology


Article Preview

More powerful process design methods and tools of sheet metal stamping are needed to help engineers design better products, to reduce lead times and costs, and to increase product performance and accuracy. A novel model for representation of object-oriented case information constitution relationship is presented, ‘Class-Property’ structure is proposed in order to refine the case representation, multi-types, properties are adopt to describe more detailed information, three hierarchies of index strategy are used to realize case extraction. Furthermore, experts’ knowledge and experience on previous design cases and forming problems are collected, which can provide designers useful practical experience and data to aid design procedure and to solve the potential problems of sheet metal stamping. In order to illustrate these applications, database technology is used to realize a prototype system of auto body panels, which can be used to integrate process design information and manufacture resources.
