轴类零件CAD／CAPP并行集成技术研究

On CAD/CAPP Concurrent Integration for Rotational Type Parts

提出了面向并行工程的ＣＡＤ／ＣＡＰＰ并行集成的新概念及其实施策略，同时对在开发一个以轴类零件为对象的计算机辅助并行工程ＣＡＣＥ原型系统过程中出现的重要问题进行了研究。

A new conception,the CE-oriented CAD/CAPP concurrent integration and the imple-menting strategies are proposed.For CAD/CAPP concurrent integration for rotational typeparts,the CE-oriented modelling of part information and the multiple knowledge source pro-cessing system as well as the coordination between them are discussed.In the part mod-elling,the feature technique is adopted and the definition of the feature function is intro-duced.The part model is a dynamic binary tree structure with shape features as its trunk andthe other features adhered to,The blackboard structure is used in the multiple knowledgesource coordination.
