Abstract
A method of monitoring the wear of a grinding wheel measures the force exerted between the wheel and a workpiece, and generates a warning signal when the measured force exceeds a predetermined threshold value. A signal proportional to the normal grinding force is obtained by measuring the electrical power drawn by the wheelfeed drive motor during grinding. The value of the force proportional signal is compared with corresponding values obtained during the grinding of one or more preceding similar workpieces. Where the grinding wheel includes an annular ridge for grinding an undercut in a workpiece, the ridge portion of the wheel will normally perform more work than the remainder of the wheel, will be liable to the greatest wear, and the force signals will be measured while such portions of the wheel are performing work. The method may be used with electroplated CBN grinding wheels.
