摘要: 本文提出了对产品零件施行逻辑分割的概念和方法,并利用属性文法理论构造了产品零件信息表示的形式化方法——机械工程文法。根据逻辑分层分割的概念,用机械工程文法表示的产品零件信息既能直接用于CAD,又能直接用于CAPP和CAM。

Abstract: In this paper, the concept and method of logical hierarchical segmentation of machine part is presented and a formal method of representing machine part ---- Mechanical Engineering Grammar is constructed with attributed grammar theory. According to the concept of logical hierarchical segmentation, the information of a machine part represented by the grammar can be used directly in both CAD and CAPP as well as CAM.

Key words: CAD, CAM
