Cryogenic grinding was able to produce a quality product with less material and also reduced the grinding force when compared to dry and wet grinding . It has been shown that cryogenic grinding is efficient in eliminating tensile residual stress in the surface by reducing the cutting zone temperature and surface roughness [27,28,29].
