Optimization Of Roller Burnishing Process Parameters On Surface Roughness Using Response Surface Methodology

The present study is to optimize the roller burnishing process parameters for improved surface quality. A Response Surface Methodology based on Central Composite Design is utilized for experiments. Four process parameters considered include feed, speed, number of passes and depth of penetration. The experiment was performed with work piece of EN19 alloy steel using new roller burnishing tool on a CNC lathe machine. A regression model has been developed to find out the optimum value of surface roughness. Using Response surface methodology concept to optimized the values of the burnishing process should be determined- feed 0.06 mm/rev, depth of penetration 0.17mm and burnishing speed 1196 rpm at single pass.
