摘　　要：提出了利用CAD系统的用户定义特征实现面向CAPP的特征设计的方法,在归纳定义常用冲压特征的基础上,建立了冲压特征信息模型,介绍了用VisualC++6.0在参数化三维特征CAD软件平台上开发的冲压CAPP系统,实际应用证明,用户定义特征是在商品化CAD系统中实现集成化CAD/CAPP系统的一种有效方法。The approach to realized feature design for CAPP system by use of the user-definedfeature is proposed. Based on some often been used manufacturing features for modelingstamping parts, the stamping feature information model is constructed. A stamping partsCAPP system based on this notion on the feature based parametric CAD software is deve-loped with Visual C++6.0 and Solidworks API, it proved the user-defined feature is a veryeffective technology to realize the integration of CAD CAPP system.
