Magnetic abrasive finishing (MAF) is a polishing/finishing technique used primarily to achieve higher levels of surface finish. The process is widely used for finishing of very hard and brittle non magnetic materials. It utilizes magnetic force and ferromagnetic abrasive particles for finishing of work piece. Ferromagnetic particles are conglomerate of abrasives and iron particles. The work piece was a non-magnetic stainless steel (SS307 grade) tube. The magnetic abrasive particles were used in present work prepared by sintering of iron and silicon carbide particles. The input parameters which were considered for the study include rotational speed of poles (RPM), MAP size (µm), quantity of iron in abrasive particles.The effect of MAF parameters have been studied on Ra, Percentage Improvement in Surface Finish. The interaction of Rotational speed , MAP size and Percentage of iron in abrasive particles have shown predominant effect on the Ra, and percent improvement in surface finish. Then the SEM analysis of the finished work pieces was done which indicates that the tool marks are completely removed by the MAF process. The maximum PISF (58.55%) was obtained at, speed = 200.45 rpm, MAP size = 200µm and 85% of iron in abrasive particles.
