Metallurgical Reasons for Grinding Cracks and Their ...

 · Grinding is a highenergy 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. Depending on the increase in temperature, changes in the residual stress state and microstructure can result. Cracking is the limiting case of residual ...
