Abstract
Magnetic Abrasive
Finishing (MAF) is one among the unconventional finishing methods, wherein the
workpiece is placed between two magnets, and the operating gap and the magnetic
flux is between the two magnets control the cutting force. Surface is finished
by eradicating the material in the form of microchips by abrasive particles in
the prevalence of magnetic field. The material is detached in such a way that
surface finishing and deburring are performed at the same time with the
functional magnetic field in the finishing zone. MAF setup is designed for
internal finishing of Leaded Tin Bronze (SAE 660) cylindrical work pieces and
it is mounted on lathe machine. The sintered powder is prepared for
experimentation by compacting of magnetic powder (Fe powder of 300 mesh size),
and abrasive powder (Al O of 300 2 3 mesh size). In order to analyze the
outcomes of operating gap and rotating speed on material exclusion, surface
finish changes and ΔRa %, a sequence of trials were performed using in-house
manufactured MAF setup. On the basis of results obtained, in general, the
method generated best results at Rotational Speed of 146 rpm, Magnetic flux of
0.2 Tesla, weight of Abrasive particles of 15 grams, and Surface finishing time
of 20 minutes.
