The method of reading the line, arc, spine, tolerances, surface roughness and full messages of the part from DXF file generated by AutoCAD is mainly introduced. Based on the study of DXF, a program interface is developed, by which the data can be shared among different CAD systems. According to the different Characters, the respective tool paths are designed. And by a machine configure file, the General postposition process is deal with. On the research of thegeneral simulation technology that is based on the NC codes. By analyzing the characteristics of the CNC system and the NC codes, a set of general simulation interface is developed.

本文主要介绍如何从AutoCAD生成的DXF文件中读取直线、圆弧、样条曲线、尺寸公差、表面粗糙度等信息及零件的全局信息，结合回转体零件的特点，通过对应用广泛的DXF的深入分析，建立了与不同CAD系统实现数据共享的编程接口；根据零件的不同加工特征提出了相应的走刀路线，并通过机床配置文件，初步实现了通用后置处理；研究了数控系统和NC代码的特点，建立了仿真通用接口，并提出代码翻译地基本思路。
