Abstract: With regard to the program translation problem brought by the change of five-axis machine, a mutual translation method of NC program among multi-object machines was presented, which used an indirect program translation mode based on transition machine. Coordinate matching ability was analyzed aiming to different spatial structures of five-axis machines. Corresponding relationships of coordinates among different machines were constructed and the algorithms of post-processor and inverse post-processor were studied. On this basis, linear axes translation algorithm and rotation axes translation algorithm were established, and mutual translation of NC program between two kinds of machines was realized. Experimental results indicated that the proposed method could effectively solve the translation problem of five-axis NC program toward multi-object machines.
