电火花雕刻加工自动编程

Automatic Programming of EDM Engraving

介绍了电火花雕刻加工的图形自动编程系统。该系统以工件图的DXF图形交换文件为输入,采用分层去除策略生成实体的截面轮廓线并对截面轮廓线进行插补以达到工件的加工精度要求,经过工艺分析和处理,自动生成NC代码,并进行加工仿真。

This paper presents an automatic programming EDM engraving system. The system gets entities informa- tion of the mechanical parts chart by reading DXF files, builds the section contour line of the solid model with the strategy of slicing, and then interpolates the contour line to satisfy the requirement of precision. It can generate NC program automatically through analyzation and process, and simulate the tools tracks.
