Abstract
Abstract: The process of burnishing is performed by applying a highly polished and hardened ball or roller with external force onto the surface of a cylindrical work piece. The burnishing process increases the surface hardness of the work piece, which in turn improves wear resistance, increases corrosion resistance, improves tensile strength, maintains dimensional stability and improves the fatigue strength by inducing residual compressive stresses in the surface of the work piece. The conventional methods of finishing process viz. grinding, broaching used to improve the surface finish of the metallic components, but the burnishing process which is having same role to play in finishing process has many advantages associated with it fulfilling above said requirement successfully. This paper presents results of the study about design and developmental issues of Ball burnishing tool. This tool is used to perform burnishing process successfully by controlling different parameters. Ball burnishing process is mainly considered in industrial cases to restructure surface characteristic. Ball burnishing process is employed on aluminum alloy AA 6063 with BFS (Blast FurnaceSlag) work piece for current study. In this thesis, work the effect of burnishing parameter like speed, and feed and the number of passes is going to be examined on the surface roughness characteristics of aluminum with BFS (Blast Furnace Slag).
