五轴高速加工中心后置处理算法研究

Research on the post-processing algorithm about five-axis high-speed machine center

针对DMC75VLinear五轴高速加工中心和Heidenhain iTNC530数控系统,提出一种后置处理算法,结合M128指令研究了刀具摆角B和工作台转角C的计算公式。利用编写的后置处理软件得到了不同零件的数控程序,已在该五轴加工中心上使用,从而验证了本研究的后置处理算法的正确性和可靠性。

The post-processing algorithm is studied ,as to the DMC75VLinear 5-axis machining center and Hei- denhain iTNC530 numerical control system. The formulas about angles B and C are proposed coordinating to the instruction of M128.The NC codes obtained from this method is proved in the DMC75VLinea machine,thus the post-processing algorithm is tested correctly and reliably.
