This research is aimed at detecting wear and breakage of cutting tools through the monitoring of cutting forces, even when the cutting variables (speed, feed, depth-of-cut) vary and the workpiece hardness changes during machining. A mathematical model of the machining process will be developed and stored in the control computer of the machine tool which will separate the wear and gbreakage effect on cutting forces from those of the other parameters, thus enabling the on-line detection of tool wear and breakage. The model will updated online as the machining progresses.

本研究旨在检测刀具的磨损和破损 通过监测切削力，即使在切削 变量（速度、进给、切削深度）变化，工件硬度 加工过程中的变化。 加工的数学模型 过程将被开发并存储在控制计算机中。 将磨损和破损的影响分开的机床 切削力与其他参数的切削力不同，从而使 在线检测刀具磨损和破损。 模型将更新 随着加工的进行在线进行。
