Research on CAD/PDM Integration Based on Designing Knowledge Base
In order to satisfy the requirements for quick product customized design,the knowledge-based integration of computer aided design (CAD) and product data management (PDM) was researched.The knowledge structure which is composed of product requirement decision knowledge,product structure knowledge,product configuration knowledge,product characteristic knowledge and product designing resources was constructed on the basis of product's information model,the decision tree and weighted clustering algorithm were used to knowledge inference and designing decision,thus realizes knowledge-based data exchange between CAD and PDM system and improve the efficiency of product design.Finally the designing of gear-box was used to verify integrated system's support to product designing process.
