Abstract
A power tool in which feed rate information is used as a means of changing cutting implement speed to maintain an optimum chip rate removal. As the tool is loaded by a feed rate increase, the motor speed will increase to that point empirically determine to provide a good finish for the material and cutting implement size selected. If the load decreases, the motor speed will correspondingly decrease to that speed which will provide a good finish for the material and cutting implement size selected with out overheating of the material. A limit would be set to indicate to an operator when he is at the upper limit of the speed and feed rate range and turn off the tool after a short period of time to prevent destructive overheating.
