Energy partition results from the previous paper are used to calculate the surface temperature distribution during grinding. The grinding temperature is calculated as the sum of a local temperature in the vicinity of an abrasive grain and a grinding zone temperature over the apparent area of contact between the grinding wheel and the workpiece. The peak local temperature at the cutting edge of an abrasive grain is found to be close to the melting point of the workpiece. By assuming that workpiece burn occurs at a critical grinding zone temperature, the energy flux at the onset of burn is related to the grinding conditions.
