Burnishing is a cold-working process in which plasticdeformation occurs by applying a pressure through a very hard and smooth ball or roller on a metallic surface. Improvements in surface finish, surface hardness, wearresistance, fatigue resistance, yield and tensile strengthand corrosion resistance can be achieved by the applicationof this process.
The experimental studies were conducted under varying Burnishing forces, speeds, feeds, and lubricants. The settings of burnishing parameters were determined by using the Taguchi experimental design method.The optimum burnishing parameter combination was obtained by using the analysis of signal-to-noise (S/N) ratio. The confirmation tests indicated that it is possible to increase surface hardness and decrease surface roughness significantly by using the Taguchi method. The experimental results confirmed the validity of the used Taguchi method for enhancing the ball burnishing performance and optimizing the process parameters.
