Abstract: High amount of energy generated in the grinding zone is dissipated as a heat which leads to thermal damage to the workpiece. Heat transfer phenomena in high speed deep surface grinding (HSDSG) is entirely different than conventional shallow cut grinding. Due to high wheel speed and large depth of cut, the temperature rise in the grinding zone becomes very high during high speed deep surface grinding. Therefore, investigation of the temperature distribution becomes important in such situations. In this paper, a two dimensional thermal based finite element model has been developed to investigate the transient temperature distribution within the contact zone as well as in the whole workpiece due to high speed deep surface grinding. After comparing the results of present model with the available results, the model is used to study the effect of different input parameters such as depth of cut, workpiece speed, heat flux profile and wheel material on transient temperature distribution.
