A feature-based parametric modeling system for CAD/CAPP/CAMintegrated system

摘要

For shortening the product development time, this paper proposes afeature based parametric product modeling system, called ZD-MCADII,which is suitable for the integrated engineering design in CIM systemenvironment. The architecture of ZD-MCADII and the characteristics ofits modules are described in detail. The ZD-MCADII product data ismanaged by an object-oriented database management system OSCAR, and theproduct model is built according to the standard STEP. As the productdesign is established on a unified product model, all product data areglobally associated in ZD-MCADII. ZD-MCADII provides various designfeatures to facilitate the product design, and supports the integrity ofCAD, CAPP and CAM
