Abstract

In magnetic abrasive finishing (MAF), abrasive grains as a tool move on surface and can remove chip from surface of work piece. In this study AL 6061 tube was considered as the work piece and the effect of finishing parameters such as gap distance between tube and poles, rotational speed of tube, abrasive ration and finishing time on surface roughness was investigated. The mixture of ferromagnetic grits (Fe) and Al2O3 grains was considered as the abrasives. The result showed increasing in rotational speed, finishing time and abrasive grains up to certain value decreases surface roughness and increasing in air gap increases surface roughness.
