数控机床辅助功能指令由CNC和PMC共同处理，但其具体运算处理过程国内还未见文献系统报道。用一具体实例对冷却液M指令的运行机制、PMC程序设计及加载、辅助功能M指令机床验证进行了详细阐述，有助于更好地使用、维护机床和利用系统提供的PMC梯形图来快速诊断故障，特别是对理解PMC程序、扩展开发机床控制功能提供了参考。

CNC machine tool auxiliary function commands are handled by CNC and PMC,but their concrete operation processes have not been reported in domestic literature system. Based on the specific examples,the operation mechanism of coolant M instruc-tion,the design and load of PMC program,the auxiliary function commands machine validation,were elaborated in detail. This will contribute to a better use and maintenance,and using PMC ladder diagram interface of NC system to diagnose fault quickly,especially it provides reference for understanding the PMC program,extending the development of machine control function.
