摘要
以钣金件为应用对象，介绍了基于工具化思想的混合式ＣＡＰＰ系统的构成，重点讨论了形状特征主干工艺模型的表达方法，以及相关知识库的构造原则及其表达组织方法。
In this paper, a hybrid CAPP system is developed by combining the generative and indexical method for sheet metal part. A process model is proposed in order to be easy to post deal. At last, the principles and method of building knowledge base used in main operation generating are discussed in detail.
