在数控机器加工中有三种弥补：这三种弥补根基上能处理在加工中因刀具形状而产生的轨迹题目。下面是三种弥补在通俗加工编程中的操纵。

起首，操纵刀具长度作为刀长弥补，能够防止在差别的工件加工中不时地点窜刀长偏置。如许一把刀具用在差别的工件上也不必点窜刀长偏置。在这类环境下，能够根据必然的刀具编号法则，给每把刀具作档案，用一个小标牌写上每把刀具的相干参数，包含刀具的长度、半径等材料，现实上良多大型的机器加工型企业对数控加工装备的刀具办理都接纳这类方式。这对那些特地设有刀具办理局部的公司来讲，就用不着和操纵工面临面地告知刀具的参数了，同时即便因刀库容量缘由把刀具取上去等下次从头装上时，只要根据标牌上的刀长数值作为刀具长度弥补而不需再停止丈量。
