Surface integrity has attracted attention of the researchers for improving the functional performance of the engineering products. Improvement in surface finish, one of the important parameters in surface integrity, has been attempted by researchers through different processes. Grinding has been widely used for final machining of components requiring smooth surfaces coupled with precise tolerances. Proper selection of grinding wheel material and grade with grinding parameters can result in improved surface finish improved surface characteristics. Present work reports the study of the effect of grinding parameters on surface finish of EN8 steel. Experiments were performed on surface grinding and cylindrical attachment for optimization of grinding process parameters for improved surface finish. Grinding wheel speed, depth of cut, table feed, grinding wheel material and table travel speed for surface grinding operation and work speed for cylindrical grinding operation were taken as the input parameters with four types of grinding wheels (Al2O3 of grade K and L, and white alumina of grade J and K). The surface roughness was taken as output parameter for experimentation. The grinding wheel material and grade have been observed as the most significant variables for both the cylindrical grinding and surface of grinding. Surface roughness in case of surface grinding is better compared to cylindrical grinding which can be attributed to vibrations produced in the cylindrical grinding attachment. Surface roughness (Ra) value of 0.757 µm in cylindrical grinding and 0.66 µm in surface grinding has been achieved.
