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 mono Block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。 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.
