Abstract

A theoretical analysis is presented of the energy partitioning and surface temperatures in grinding. The numerical results agree with the experimental results of Kohli et al. It is found that the presence of the fluid inside the grinding zone can reduce the heat flux into the workpiece and the workpiece temperature significantly. However, it is nearly impossible to keep the fluid active for the conventional grinding of steel with aluminum oxide. For the conventional grinding of steel with CBN, or the creep feed grinding of steel with aluminum oxide or CBN, it is possible to keep the fluid active and therefore to reduce thermal damage. To help understand the effects of grinding conditions, a simplified heat partition model is developed which is proved very accurate for down grinding and fairly accurate for up grinding. The effects of grinding conditions on the energy partition to the workpiece and the workpiece temperature are studied systematically.
