Abstract
In the manufacturing sector, surface grinding is used for surface finishing operation. In this paper, Surface quality and material removal rate are the two response parameters considered in the analysis. High Carbon High Chromium steel material is selected for the grinding operation. In this work, empirical models are developed for surface roughness and material removal rate by considering Depth of Cut, Wheel Grade and Grit Size as control factors using Response Surface Methodology. Response Surface Methodology is applied to determine the optimum machining parameters leading to minimum surface roughness and maximum material removal rate. Depth of cut is most effective parameter for Material Removal Rate but Grit Size has minor effect on MRR. Surface quality is very important factor which is affected by Depth of Cut and Grit Size. In this study, force analysis is also done to see the effect of the control factors. Depth of Cut is the most affecting factor on Radial and Tangential Force but Grit Size has minor effect on the force. ANOVAis applied analysis and T-test and F-test values are obtained for checking the optimal value of the parameters.
