ABSTRACT:
A method of monitoring the performance of a cutting tool which moves relative to a workpiece through a cycle includes the steps of dividing the cycle into a plurality of increments, sensing a function of force applied to the tool during the increments, mathematically smoothing the function of force sensed during the increments, and establishing a trend in the mathematically smoothed function of force for the plurality of increments. The mathematically smoothed function of force is compared with the established trend and if the mathematically smoothed function of force deviates substantially from the established trend a first signal is generated.
