基于传动箱体零件的CAD／CAPP系统设计

CAD/CAPP System Design Based On Transmission Box Parts

本文介绍了一种基于特征实例的CAD／CAPP系统。在特征库的支持下，用户可完成箱体零件特征造型，形成描述性文件，系统根据描述的特征信息与特征实例库进行匹配，以获得各特征加工链，再利用工艺决策模块进行排序优化，最终获得所需加工工艺。

This paper describes an instance of a feature-based CAD/CAPP system.Support in the feature database,users can complete The feature modeling,the formation of a descriptive file,the system characteristic information in accordance with the characteristics described in the case library to match in order to obtain the characteristics of processing chain,re-use ordering process decision-making module is optimized, finally obtain the required process.
