Grinding is often a final machining step to achieve desired surface finish or final dimensions. Grinding is a high-energy process where a lot of frictional energy is concentrated over a small region [1]. This localized energy is confined to the surface layers of the part being ground, resulting in a local rise in the surface temperature.
