Abstract
A system for finish grinding a workpiece monitors the actual radius of the workpiece as the finish grinding progresses; feeds the grinding wheel into the workpiece at a feed rate which decreases, preferably at an exponential rate, as a desired final radius of the workpiece is approached; and terminates the feeding of the grinding wheel at the desired final radius of the workpiece. In a preferred embodiment, the grinding wheel is trued, simultaneously with the finish grinding, by feeding a truing element into the grinding wheel at a rate that varies as a function of the decreasing rate at which the grinding wheel is fed into the workpiece. The truing element is preferably advanced toward the grinding wheel at a rate which has (1) a first component corresponding to the rate at which it is desired to remove material from the grinding wheel at the truing interface and (2) a second component corresponding to the wear rate of the grinding wheel due to grinding, the second component varying as a function of the rate at which the grinding wheel is fed into the workpiece. The grinding wheel is preferably advanced toward the workpiece at a rate which has (1) a first component corresponding to the decreasing feed rate at which the wheel is fed into the workpiece and (2) a second component corresponding the rate at which material is removed from the grinding wheel at the truing interface. The wear rate of the grinding wheel due to grinding is determined from a power function relationship between the wheel wear rate and the wheel feed rate for a particular grinding operation.
