CAD/CAPP集成与工艺文件并行处理的研究

The Research of CAD/CAPP Integration-oriented Feature Modeling System

基于VBA开发环境,介绍一种实用型的CAD/CAPP集成方法.CAPP子系统的工艺知识由专家系统的推理器推理,自动形成工艺决策内容,并用VBA将工序图、工艺文件在Word环境中输出,便于编辑、打印.解决了CAD/CAPP集成中图文格式同步输出的缺陷和不完整性的问题.系统用VB语言通过接口程序生成DXF数据交换文件,并用VBA实现在AutoCAD环境下生成零件图.以港口机械轴类零件为例加以说明.

This paper introduces a developing way of CAD/CAPP integration oriented feature modeling system based on Auto CAD system using Visual Basic ＆ Visual Basic for Application as the developing tool. The system puts together the geometric information and the basic process information, builds a unified data model with DXF standard to realize the information integration and concurrent moving of CAD/CAPP.
