Process for controlling wear and surface conditioning of a super abrasive grinding wheel, active and process of clearing double to condition the surface activates a super abrasive grinding wheel

摘要

A dual compensation method of surface conditioning a super-abrasive grinding wheel 17 by intermittently moving the wheel to a stationary wheel conditioner unit 20 mounted adjacent the grinding wheel and having a consumable element 47 engaged by the grinding wheel comprises the steps of grinding a predetermined number of workpieces W to establish a first predetermined depth of super-abrasive wheel wear, and periodically conditioning the wheel surface by consuming a second predetermined depth from a consumable reconditioning tool surface. A first compensation for grinding wheel wear is produced 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. The grinding wheel is conditioned 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.
