摘　　要：从机床坐标系、工件坐标系及编程坐标系出发,分析了数控镗铣类机床及加工中心在同一个工件坐标系下使用多把长度不同的刀具对工件进行加工时进行刀具长度补偿的原因。论述了有基准刀与无基准刀长度补偿的原理,研究了这两种方法的特点,提出了机床Z坐标的计算方法。讨论了撤消长度补偿后CNC控制刀具所走的编程坐标表达的实际意义,这对理解数控加工刀具长度补偿及数控编程具有实际指导意义。Building the machine coordinate system, workpiece coordinate system and program coordinate system, the paper discussed the reason of bulding the cutting tool length compensation by using muff-tools in same coordinate system in NC boring- milling machining centers. Discussing the principle of the length-compensation with and without the reference tool and studing the double methodological characteristics, the paper presented the Z coordinate calculation method in NC machine and the cutting tool locus in the program coordinate system without the length-compensation. It will be instructive for understanding the cutting tool length-compensation in numerical control machining and the numerical control programming.
