PURPOSE:To enable to perform dressing accurately, by a method wherein a grinding wheel is cut into by a dresser by a depth equivalent to a removing quantity for dressing after movement of the dresser by a quantity of abrasion from a position where preceding dressing of a rotary grinding wheel is completed and a regulating wheel is moved according to the movement. CONSTITUTION:A dressing device 17 is moved in X and Y directions from a preceding dressing position F of a dressor 6 of a grinding wheel which has been measured by a length measuring device 7 and applied to a microcmputer 16, and when the dresser touches a rotary grinding wheel 1, a sound of which is detected by an AE sensor 15, applied to the microcomputer 16 and a feed of a pulse motor 8 in a Y direction is suspended. A quantity of abrasion DELTAh of the rotary grinding wheel 1 including accuracy alpha of the sensor is obtained by the microcomputer 16 here, and then the rotary grinding wheel 1 is fed by a removing quantity X for dressing in the Y direction by the pulse motor 8. Then, a regulating wheel 2 is made to advance by DELTAh+X by a pulse motor 11. Then, dressing can be done accurately, and quality can be improved without generating burn on a work to be ground. |
