基于特征匹配的CAPP系统工艺派生方法设计与应用

Design and Application of Process Derivation Method in CAPP System Based on Feature Matching

针对现存的气门零件CAPP系统存在难以对企业经常生产的气门零件直接分组建立数据库的问题,基于成组技术开发了气门零件分组程序。针对进行气门零件CAPP系统特征匹配后不能明确指出现存工艺文件所需修改位置的问题,基于数控技术拟出了气门零件特征与机加工的关系并做出新的气门零件特征匹配程序。

In view of the situation that existing CAPP system for engine valve is difficult to directly group and establish a database problem for the valve parts made by the enterprise,a valve part grouping program was developed based on grouping technology.For the problem that CAPP system characteristic cannot indicate clearly after matching the positions needing modification for the existing process files,the relationship between valve part characteristic and machining was simulated based on numerical control technology,and a new matching program of valve parts characteristic was developed.
