Abstract: The study of grinding contact zone temperature and temperature distribution in the workpiece during high efficiency deep surface grinding (HEDSG) is important for the quality of the product and wheel wear. As a consequence of the high temperatures present in HEDSG, not only wheel wear increases, but large residual stresses may also develop in the workpiece resulting in surface cracks. Even microstructural changes occur if the temperature is sufficiently large. The present work aims to develop a two-dimensional (2D) thermal finite element method (FEM) model for the simulation of temperature in the contact zone as well as in the whole workpiece during HEDSG. The present model has been used for the calculation of temperature distribution in the workpiece during a deep grinding scenario and the results compared with the available results in literature. The effect of temperature dependent thermal properties and heat flux profile on temperature distribution in the workpiece has also been investigated. Parametric studies were carried out to study the effect of different input parameters such as depth of cut, work feed rate, material of grinding wheel and type of cutting fluid on temperature distribution, in the contact zone and in the workpiece.
