Cylindrical grinding process requires a large amount of specific grinding energy and the energy is dissipated as heat in the work surface resulting in increasing the surface temperature and localized plastic deformation. An increase in temperature at grinding interaction zone causes deterioration of the surface integrity, leading to grinding burns, induction of tensile residual stress and geometrical inaccuracies, so it’s become important to understand the factors which affect grinding temperature. The objective of this work is to undertake comprehensive analysis of grinding parameters and associated phenomena during grinding process that influence heat flow in and out of the grinding zone and its effect on grinding burns. In this regard, screening experiments were conducted for obtaining the most influential grinding variables such as thermal damages, surface roughness and form error. Further, these variables were used for the detailed experimental study. In addition, the work also focuses on theoretical evaluation of maximum surface temperature so that the onset of grinding burn can be identified. It is known that direct measurement of grinding temperature is always difficult during experiment method as the work-wheel interaction zone is fairly hidden and flooded with the coolant. Therefore, the evaluation of temperature would help the in early detection of possibility of the grinding burns.
