摘要
CAD系统与CAPP系统的集成是企业内部各种应用系统集成的基础,制造特征的识别是实现CAD/CAPP集成的关键技术。本文应用基于属性邻接图的方法在AC IS平台上对轴类零件的制造特征进行识别,有效地识别出该类零件的主特征和常见的辅助特征,并利用AC IS提供的类库提取模型底层的几何参数,从而得到定义各项特征所需的几何尺寸信息。最后以XML中性文件的形式输出识别结果,为后续进行的工艺自动生成提供初始数据。
The integration of CAD and CAPP is the foundation for the integration of various kinds of application systems in an enterprise, and machining feature recognition is key to CAD and CAPP integration. This paper describes an attribute adjacency graphic-based （AAG-based） method for machining feature recognition of shaft parts on the ACIS platform. The method effectively recognizes the major and minor features of the parts. All the geometrical information for defining various features are obtained by using the class library provided by ACIS. Finally an XML neutral file that describes recognition results is provided for the subsequent CAPP processes.
