Abstract: After preliminary experimentation, a detailed study through statistical design of experiments was conducted for nanofinishing of stainless steel workpieces through Magnetorheological Abrasive Flow Finishing (MRAFF) process. Response surface regression analysis was done to analyse the effect of number of finishing cycles, extrusion pressure and magnetic flux density on percent change in surface roughness. |F| test from the Analysis of Variance (ANOVA) was conducted and contribution of each model term in affecting percent improvement in surface finish was calculated. The experimental results were discussed and optimum finishing conditions were identified through contour plot. The best surface finish obtained on the stainless steel workpieces with the present set-up configuration is 30 nm.
