摘要： ：在工业生产中，需要将CAD/CAM 软件生成的CL 数据通过后处理程序转换为NC
加工代码。针对自由曲面五轴加工的数据转换问题，应用D-H 修正标记法开发五轴加工机床后
处理程序，对D-H 修正标记法的参数定义过程进行了描述并提出改进，针对DMU 80 monoBlock
型五轴加工机床开发了专用后处理程序，最后通过VERICUT 进行了加工仿真，验证该程序的
正确性。该程序对提高自由曲面五轴加工数据后处理的效率具有重要意义。

Abstract: Transforming the CL data produced by CAD/CAM software into NC codes is needed in
industrial areas. The application of D-H modified notation method in five-axis machine tools
postprocessor development is studied. The process of parameter definition is described in D-H
modified method and the improvement is put forward. A special postprocessor of DMU 80
monoBlock five-axis machine tool is developed. At last, a simulation is made to verify the validity of
the postprocessor by VERICUT. This program has some guiding significance in increasing the
efficiency of data conversion in free-form surface five-axis machining.
