Effect Evaluation of Roller Burnishing Process on Surface Roughness of 6061 T6 AL Alloy using Response Surface Methodology

Surface treatment is an important aspect of all manufacturing processes to impart special physical and mechanical properties. Roller Burnishing Process is a post-machining operation in which the surface irregularities of workpiece are compressed by the application of a roller, which produces a smooth surface and simultaneously induces compressive residual stress. This paper describes a systematic methodology for empirical modeling and effect of the Roller Burnishing process parameters. The design of Roller Burnishing Process parameters is based on response surface methodology, which integrates a design of experiment, regression modeling technique for fitting a model to experimental data. Central composite rotatable design has been employed to develop a second-order surface roughness model. Response surface methodology was employed to analyze the effect of parameters to ensure a minimum surface roughness.
