ABSTRACT:
This invention provides a grinding method and a grinding machine therefor with controlled grinding force which detects the grinding force and grinding rate during operations, calculates in real time the threshold force and grinding wheel sharpness coefficient for each grinding cycle by an arithmetic operation unit, monitors the changes in sharpness of the grinding wheel, and properly changes values instructed by the grinding force commands based on the threshold force, the sharpness coefficient and the predetermined grinding rate value for controlling the feed of the grinding wheel. When the deflection of the grinding wheel shaft changes due to the changes in grinding force, the swivel angle of the grinding wheel shaft or a workpiece is adjusted to prevent the surface of the workpiece from tapering.
