... integrity, productivity and economy also are important factors. Wheel wear is measured by a grinding ( G ) ratio, that is, the volume of metal removed from the workpiece to the volume of the grinding wheel, that is worn away during the process. In grinding superalloys, the G -ratio varies from 2 to 70...
