Abstract
A method of monitoring the performance of a tool which moves relative to a workpiece through a cycle and controlling the feed rate between the tool and the workpiece includes the steps of dividing the cycle into a plurality of increments, sensing a function of force applied to the tool during the increments, determining a mathematically smoothed function of force for the function of force for each sensed individual increment of the cycle and establishing a reference for the mathematically smoothed function of force for each of the sensed increments. The actual determined sensed mathematically smoothed function of force for a particular increment is compared with the established reference for that particular increment and a first signal is generated if the actual determined mathematically smoothed function of force deviates from the established reference. The feed rate between the tool and workpiece is modified in dependence upon the first signal.
