High temperatures in grinding can cause thermal damage to the workpiece. This paper presents an overview of quantitative methods to calculate grinding temperatures and the energy partition to the workpiece. It is shown that the energy partition, and consequently the grinding zone temperature, depends on the type of abrasive, fluid application conditions, and grinding parameters. For regular grinding with conventional aluminum oxide abrasive wheels, the energy partition typically ranges from 60 to 85%. However for creep-feed grinding with slow work velocities and large depths of cut, cooling by the fluid at the grinding zone reduces the energy partition to less than 5%.
