STEP特征模型及其在集成环境中的应用研究

Research on STEP Feature Model and Its Application in the Integrated Environment of CIM

从 STEP特征模型、CAD/CAPP特征建模、STEP工具集的构造、模型映射等角度 ,论述了 STEP技术在CIM领域的应用 .在此基础上 ,阐述了“即插即用”的特征映射及信息集成技术 ,并讨论了一种在 STEP工具集的支持下 ,以独立于具体系统的方式实现 CAD/CAPP特征信息集成的方法 .

This paper addresses the application of STEP techniques in CIM environment and explores the principles of establishing STEP feature model, realizing feature based modeling in CAD/CAPP, implementing STEP toolkit and carrying out model mapping. Based on these approaches, a kind of “Plug and Play” technique for feature mapping and information integration is discussed. Finally, a system independent method to feature based CAD/CAPP integration is presented.
