二维特征造型方法的研究

Study of 2D Feature Modeling Method

本文根据实际需要对二维特征造型方法进行了研究,目的是改造传统CAD系统,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,提出形状特征作为精度特征的载体,第一步是用形状特征设计,第二步是进行精度特征识别以得到完整意义上的特征,进而满足CAP的需要。

In this paper the 2D feature modeling method is researched in order to reconstruct traditional CAD system and support CAD/CAPP integration. The adopted scheme is the integrating of feature design and feature recognition. Form feature is the carrier of precision features. First, we can design by form feature; then, we can get the feature in real sense by precision feature recognition to meet the requirement of CAPP.
