In a single roller burnishing process, a hardened and polished roller is penetrated against a revolving cylindrical workpiece. Rotation of tool is parallel to the axis of rotation of the workpiece. Roller burnishing process is a superior chipless finishing process. It is done on machined or ground surfaces for both external and internal surfaces. Roller burnishing is used to improve the mechanical properties of surfaces as well as their surface finish. In this experiment cylindrical Aluminum alloy (Al - 6061 ) workpiece has been burnished using different machining parameters [Speed, Feed, and Depth of Penetration and Number of passes.].The experiment was carried on lathe machine. It is observed that Depth of Penetration is the significant parameter to control the surface finish (Ra value). The AVOVA results are validated using the AHP method. Here regression model also derived and presented. At the end the confirmation tests conducted to confirm results with the actual Ra values.
