摘要
特征与面向对象的技术有许多相通之处 ,他们是当前设计CAD/CAPP/CAM的两大工具。研究运用面向对象技术实现特征表示的目的就是通过面向对象技术建立适用于产品数据交换的计算机内部数据表达模式。
There are many analogies between features and an object oriented technique which are two kinds of tools to design CAD/CAPP/CAM. The goal of research on feature representations using the object oriented technique is to establish data model of product data exchange in computer. In this paper, the method of expressing features and constrains between them in feature class construction is discussed.
