The Realization of Research for CNC Machining Systems Based on DXF File

Yunming Du

Abstract

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.
