摘要
从CAD系统的图形数据库中提取零件的几何信息和工艺信息,是实现CAD/CAPP/CAM系统集成的一种方法.本文介绍了如何从AutoCAD生成的DXF文件中读取直线、圆、圆弧、椭圆弧等信息,结合面向对象的程序设计方法,将所读取的图元信息转化成数控加工代码.
Extracting the geometric information of parts and processes information from the CAD system database is a method to integrate CAD/CAPP/CAM systems. This article described how to read such information as a straight line, circle, arc, elliptical arc from AutoCAD' s DXF file. Combined with object - oriented programming methods, the proposed method will read the pixel information and transfer it into CNC machining code.
