非正交机床由于机床结构的独特性,其五轴加工后置处理是个难点。在对德玛吉非正交双转台加工中心结构特性、海德汉iTNC530控制系统特性及五轴定位铣削编程特点进行分析的基础上,提出其五轴定位铣削的后置处理算法。利用Visual C++6.0开发出单独的后置处理程序,将加工刀轨的刀位文件处理生成海德汉格式的G代码文件。利用数控仿真软件Vericut 7.0建立机床的仿真模型,结果后置处理程序生成的G代码文件通过了仿真验证,证明了后置处理算法是正确的。
Non-orthogonal machine Due to the unique structure of the machine, its post-processing of five-axis machining is a difficult task. Based on the analysis of the structural characteristics of Demag Ji non-orthogonal dual turret machining center, the characteristics of HEIDENHAIN iTNC530 control system and the programming characteristics of five-axis positioning milling, the post-processing algorithm of five-axis positioning milling is proposed. The use of Visual C + +6.0 developed a separate post-processing program, the processing tool path file processing generated Heidenhain format G code file. The numerical simulation software Vericut 7.0 is used to build the simulation model of the machine tool. The results of the G code file generated by the post-processing program are verified by simulation, and the post-processing algorithm is proved to be correct.
