Roller burnishing is a surface finishing process that involves plastic deformation of the surface without any removal of the material. The level of surface finish that can be attained in roller burnishing operation depends on several process parameters. Processing at the optimum combination of process parameters is critical for achieving a higher yield during manufacturing. Hence, the present study is carried out to obtain the optimized process parameters during roller burnishing of aluminium alloy AA6061-T6, with an objective to produce a high level of surface finish. The Taguchi method has been used to assess the role of burnishing speed, feed rate, and load on the surface finishing of the alloy. Analysis of variance (ANOVA) and signal-to-noise ratio (S/N) have been employed to analyze, obtain significant parameters, and find out optimum combination levels of the process parameters. The results show that the surface quality of the specimens is significantly improved with burnishing parameters. The analysis of the results shows that the burnishing feed rate has the highest impact on the surface roughness with a contribution of 54.51%, followed by load and burnishing speed.
