Abstract: This paper describes burnishing process as an alternate super finishing process for aluminium reinforced metal matrix (Al-(SiC)_p) composites. The advantage of the burnishing process is non-chip removals to attain surface finish whereas other finishing process depends on chip removal to attain the desired surface finish, which may cause further surface abrasion and geometric tolerance. The effect of various input parameters such as burnishing speed, lubricants and number of passes on the output parameters such as surface roughness and surface hardness is studied.

Keywords: roller burnishing; MMCs; metal matrix composites; super finishing process; aluminium matrix composites; burnishing speed; lubricants; number of passes; surface roughness; surface hardness.
