【摘要】 <正> 计算机辅助工艺过程设计(CAPP)是企业工艺过程设计改革的有效途径,它能实现工艺的优化和标准化,避免工艺过程设计中的重复劳动,防止工艺过程的多样性,从而使工艺过程设计时间缩短,费用减小,质量提高。同时,CAPP是连接CAD和CAM必不可少的纽带,为计算机集成制造系统的实现创造了条件。本文是笔者通过图形素法为某厂建立的一个半创成式CAPP系统的扼要介绍。更多还原

【Abstract】 The concept of figure elements and the relationships between structure of machine part and figure element, between figure element and processing plan, between processing plan and technological process are discussed in this paper. Themethod of dividing machine parts into a certain amount of figure elements is proposed. And under the support of the expert system we put forward a method of how to make a serices of principles of strategic decision, a method of estabfishing the knowledge base of processing plan for figure elements and the knowledge base of working step and sequence arrangement so as to form the technological procedure for machine parts with revolved body.更多还原
