摘　　要：提出了一种基于计算机辅助制造的数控加工代码自动生成的方法,着重阐述了该方法针对椭圆弧的数控代码自动生成过程。该方法通过分析加工图形的dxf文件,提取图形的坐标信息,再经过数据拟和,自动生成该图形的数控代码。该方法由VC++6.0实现相应的功能,经实际运行表明,能满足加工精度要求。该方法摆脱了传统数控机床从加工图形到形成数控加工代码时间长且精度不高的缺点,极大地提高了工作效率。This paper introduces a way of automatically creating NC code based on CAM and tells how to creating NC code for ellipse arc in detail. By analyzing the DXF of the graph, extracting the information of the coordinates from DXF, and fitting dates, it can automatically generate the NC code. It has been proved that the way can meet the command of the industry. The method gets rid of weakness of long operating time and low precision of traditional numerical control machines, and dramatically improves the efficiency.
