Grinding Burn, Fig. 1

Power balance of the grinding process. (Modified from Klocke (2009). Reproduced with kind permission of IWF, ETH Zürich). \( {\dot{q}}_{tot} \) = total heat generation, \( {\dot{q}}_c \) = heat flux into the coolant (or metalworking fluid), \( {\dot{q}}_t \) = heat flux into the grinding wheel, \( {\dot{q}}_s \) = heat flux into removed material, \( {\dot{q}}_w \) = heat flux into the workpiece, F_c = cutting force, v_c = cutting speed
