Abstract
An improved method to surface condition a super-abrasive grinding wheel by intermittently moving the wheel to a stationary wheel conditioner unit mounted adjacent the grinding wheel with the conditioner unit having a consumable element engaged by the grinding wheel to condition the grinding wheel including a dual compensation method having the steps of grinding a predetermined number of workpieces to establish a first predetermined depth of super-abrasive wheel wear; periodically conditoning the wheel surface by consuming a second predetermined depth from a consumable reconditioning tool surface; and producing a first compensation of a grinding wheel by controlling the position of the super-abrasive wheel with respect to the workpiece to maintain an apparent wheel wear depth within the range of desired workpiece tolerance and producing a second compensation of a grinding wheel conditioner by contacting the wear surface of the super-abrasive wheel with the reconditioning tool surface and advancing it into and away from the tool surface a distance equal to the second predetermined depth each time that the wheel is reconditioned so as to assure that individual grains of the super-abrasive constituent of the wheel will extend beyond the bonding material constituent of the wheel to maintain cutting efficiency of the wheel following the reconditioning step.
