Parametric Optimization of Process Parameter for Roller Burnishing Process

Burnishing is a very simple and effective method for improvement in surface finish and can be carried out using lathe machines. In this project work, a roller burnishing tool is used to perform roller burnishing process on Al alloy material under different parameters. Moreover, the burnished surface has a high wear resistance and better fatigue life. It has been used to impart certain physical and mechanical properties, such as corrosion, friction, wear and fatigue resistance. One of the most effective representatives is the roller burnishing. This can simply achieved by pressing a hard and highly polished ball or roller against the surface of metallic work pieces. The impact of burnishing speeds, burnishing force and number of passes of the tool on the surface qualities and tribological properties were investigated to determinate the influence of each process parameter, several tests were carried out. Once the optimum parameters were established, a complete analysis of the surface characteristics was performed. Roller burnishing is an economical process, where skilled operators are not required. Applying Taguchi's design of experiments and analysis of variance (ANOVA) on the specimens, the aim is to find optimized values for enhancing the surface quality and hardness economically. This process can be effectively used in many fields such as Aerospace Industries, Automobiles Manufacturing sector, Production of Machine tools, Hydraulic cylinders, etc.
