查询词典 key protrusion

To meet the needs of CAD/CAPP concurrent designing in Computer Aided Concurrent Engineering. This paper investigates the key of integration system designing. The representation scheme for defining and operating form feature based on manufacture, the protrusion form feature exchanging and the UI of the system with a manufacture enviroment are presented. And also an OODM—UIMS developed by the author is introduced. The concurrent design of CAD/CAPP is the bottleneck in integrating process.

本文根据并行工程的要求，从构造基于并行、面向特征的CAD/CAM集成系统的思想出发，对系统的模式设计、基于加工的零件参数化特征描述、凸起形状特征的转换处理及具有加工环境的系统交互界面及面向对象的交互界面管理系统的设计与开发等关键技术进行了深入的研究，形成了系统的思想理论和方法。
