Abstract
An improved method and apparatus senses the extent of actual wear of a grinding wheel at an area where the wear will be the greatest during the grinding of a workpiece. The grinding wheel is dressed by removing material from the grinding wheel to an extent which is a function of the extent of sensed wear at the location where the wear is the greatest. The apparatus includes a probe member which is movable toward the circular working surface or side of the grinding wheel from a retracted position and a detector assembly which detects when the probe member initially engages the circular side of the grinding wheel. In some embodiments of the invention, the probe member is moved toward the grinding wheel in incremental steps with sufficient time between the steps to enable the grinding wheel to rotate through slightly more than one complete revolution. In one embodiment of the invention the detector assembly includes a mass which is connected with a probe member. Upon initial engagement of the probe member with the circular side of the grinding wheel, relative acceleration occurs between the mass and probe member. In another embodiment of the invention the detector assembly includes a …
