ABSTRACT:
A method of monitoring the performance of a cutting tool which moves relative to a workpiece through a cycle including the steps of dividing the cycle into a plurality of increments, sensing the function of force applied to the tool during each of the increments, determining and storing the highest function of force and lowest function of force applied to the workpiece during each of the increments, setting a maximum differential function of force limit, calculating the difference between the highest and lowest function of force sensed during each increment and comparing the calculated function of force differential with the set maximum function of force differential and establishing a signal when the calculated function of force differential exceeds the set maximum differential. In the preferred embodiment, the function of force is torque.
