本文介绍了利用激光测量仪进行刀具磨损监测和铣削过程中的刀具磨损补偿。通过改变铣刀直径来监测侧刃刀具的磨损。激光测量仪测量空气切割时旋转的铣刀直径。讨论了刀具磨损的序贯预测和监测间隔的序贯确定，以将监测方法应用于实际应用。刀具磨损补偿系统采用监控方法开发，以保持径向切削深度恒定。刀具磨损补偿显示在周边铣削操作中。

This paper presents tool wear monitoring with laser measuring instrument and tool wear compensation in milling process. Tool wear on the side cutting edge is monitored by the change of diameter of milling cutter. Laser measuring instrument measures diameter of milling cutter which rotates during air cutting time. Sequential prediction of tool wear and sequential determination of monitoring interval are discussed to apply the monitoring approach to practical use. Tool wear compensation system is developed with the monitoring approach to keep radial depth of cut constant. Tool wear compensation is shown in a peripheral milling operation.
