【摘要】 该文在总结了目前流行的一些产品建模方法后，提出一种适应于协同ＣＡＤ／ＣＡＰＰ／ＣＡＭ 系统的建模方法。它引入形状特征的概念，完成产品的形状特征造型，采用特征分类和映射工具将产品的形状特征模型转换为工程特征模型并映射到不同领域的应用中，以实现产品的协同设计与制造。更多还原

【Abstract】 In this paper,according to the recent research and development in product modeling,a new method of product modeling adapted to the cooperative CAD/CAPP/CAM system is introduced.This paper uses the concept of form feature to build feature model and the tools of feature classification and feature mapping to transform form feauture model into engineering feature model and at the same time,maps them into different fields’ application to achieve cooperative design and manufacturing of a product.更多还原
