Energy and temperature analysis in grinding
absence of thermal damage can be achieved. HEDG can achieve low specific grinding energy compared with shallow grinding and creep grinding. The chips take away most of the heat generated in the grinding process. As in creep grinding, bum-out of the coolant causes a steep rise in contact temperature of the workpiece. 1 Introduction
