| 摘 要： | 提出一种支持用户自定义ＣＡＰＰ数据结构，及与多种ＣＡＰＰ系统集成的方法，通过对ＣＡＰＰ系统的数据模型（用Ｃ／Ｃ＋＋描述）进行分析，获取其词法与语义信息，按照ＣＡＰＰ系统数据模型的数据要求，在集成系统的末端给出工艺数据，以工艺特征树为操作核心，实现了ＣＡＤ系统与多种ＣＡＰＰ系统之间的数据交换。同时，该技术在产品数据的交换中支持ＳＴＥＰ标准，实现了基于ＳＴＥＰ的信息集成。

| Abstract: | This paper proposes a method of the integration of CAD/CAPP. which is used to integrate a feature based CAD system with a variety of CAPP systems by supporting the data structure defined by CAPP. The method's kernel idea is a CAPP feature's tree. The method is employed by a STEP application. In the end. an applied example is presented. |
