二维特征造型系统开发

Development of 2D feature modelling system

对二维特征造型方法进行了研究,介绍了二维特征造型系统的开发过程,以支持CAD/CAPP的集成。采用的方案是特征设计和特征识别相结合,先用形状特征设计,再进行精度特征识别,以得到完整意义上的特征。

A research was carried out on the method of 2D feature modelling and the process of development of 2D feature modelling system has been introduced in order to support the integration of CAD/CAPP. The scheme being adopted is a combination of feature design and feature recognition. In order to obtain the feature in complete sense, the design of shape feature is employed firstly and than carried out recognition of precision feature.
