Energy and temperature analysis in grinding

2014-5-17  3 Energy dissipation as heat Power input to the process is dissipated as heat at the grain-workpiece interface. Heat spreads in the grinding contact area. The heat is conducted or convected by the workpiece, the wheel, the chips and the fluid. The initial heat generation is virtually adiabatic leading to high grain contact
