grains of the grinding wheel and the flank of workpiece (Ref. 3). At the onset of grinding burn, the grinding forces and the rate of wheel wear increases abruptly, thereby deteriorating the surface finish of the gear flank (Ref. 4). It generates a re-hardened zone near to the surface and a softened, tempered zone beneath it (Refs. 4, 12).
