Effect Evaluation of Roller Burnishing Process on Surface Roughness of 6061 T6 Al Alloy Using Response Surface Methodology

TLDR: In this article, three machining parameters were considered for tungsten carbide single roller burnishing tool: spindle speed (RPM), feed (mm/rev) Burnishing force (kgf), No of tool pass.

Abstract: The 6061 T6 Aluminum alloy(Al 97.5%, Cr 0.1%, Cu 0.15%, Fe 0.5%, Mg 0.8%, Mn 0.15%, Si 0.5%, Ti 0.15%, Zn 0.15%) round bar of 40 mm o size has been used as a work piece material for the present experiments with tungsten carbide single roller burnishing tool[6]. Al 6061 T6 is special hot-worked aluminum with good hardness and toughness properties. It is used for extreme load conditions such as hot-work forging, extrusion etc. The working life and dimensional accuracy of Al 6061 T6 can be improved with suitable heat treatment. A. Machining Parameters and Experimental Design The three machining parameters considered for this study were Spindle speed (RPM), feed (mm/rev) Burnishing force (kgf), No of tool pass. The parameters were set at five levels each. The summary of the parameters are shown in Table 1.
