Burnishing is a plastic deformation process that can be used to finish surfaces by plastic deformation
of surface irregularities. The burnishing is chipless machining which can be used to improve the surface
roughness and surface hardness on any metal work piece. The purpose of the research was to demonstrate the
roller burnishing process on Cu-Zn-AL to enhance the mechanical properties of Cu-Zn-Al shape memory alloy
and improve surface quality and surface microhardness. The experiments were carried on Cn-Zn-Al SMA using
CNC turning machine with various spindle rotations, feed rates and depth of penetration, where a roller
burnishing tool was designed and manufactured to be used in this investigation. It was found that the surface
roughness and microhardness on various Cu-Zn-Al SMA were improved by high spindle speed, The best results
were attained at 212 N burnishing force, 50 mm/min feed rate and 1120 rpm.
Key words: Burnishing process, microhardness, shape memory alloys, surface quality, , ,
