Abstract: High amount of energy generated during creep-feed surface grinding is dissipated as heat in grinding zone. Due to high and uneven temperature, thermal stresses are generated in the workpiece. Thermal stresses can lead to micro-cracks, decrease in strength and fatigue life of the components. Therefore, investigation of the thermal stress distribution in the workpiece becomes important in such situations. In the present work, thermal stresses have been predicted using temperature as input. A two-dimensional finite element-based temperature and thermal stress model has been developed to investigate the thermal stress distribution within the workpiece due to creep-feed 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, wheel speed and wheel material on thermal stress distribution.
