Research on Information Modeling and Implementing Technologies of PDM System

Based on the basic concepts of the PDM, it studies the information modeling technologies. Airmed at the practical circs in the NC Technology Laboratory of Northwest Polytechnical University, taking product design and NC maching process for examples, it establishes the personal management model, the product object model, the product-structure object model and working process model. With the effective application and implementation, the NC Technology Laboratory have been integrated in the computer integrated information management. This improves the equality and efficiency in the product design and maching process.
