面向CAPP的箱体类零件特征建模系统的开发

Development of CAPP oriented box parts feature model system

基于特征建模的CAD系统能为CAPP系统提供必要的信息。本文介绍了用面向对象技术所描述的特征及其相互关系,利用MDT的参数化造型功能实现特征创建和编辑的方法。在此基础上应用ObjectARX和MCADAPI开发了箱体类零件特征建模原型系统。

The necessary information can be supplied by the feature model CAD system. The features which can be described by the object-oriented technology, relationship between them and the methods of feature creation and feature modification by means of the parameter model fuction of MDT, are introduced here. On the basis of these, the featuremodelprototype system of boxparts is developed by ObjectARX and MCADAPI.
