Product information modelling and integration of CAD/CAPP/CAM

Integration of CAD/CAPP/CAM requires a common product information model with CAD as the key process in forming the model. CAD can not only meet the demands of design, but also meet the demands of the subsystems, such as CAPP and CAM. The product modelling system based on STEP (PMSS) uses the I-DEAS system and adopts STEP as its mechanism to exchange product information. PMSS closely integrates with I-DEAS and takes advantage of the functions of I-DEAS to meet the demands of CAD/CAPP/CAM integration. For integration with other systems, PMSS uses management tool for STEP file to manage information required by subsystems.
