Influence of boron carbide on surface roughness and metal removal rate during magnetic abrasive machining process

Abstract

Magnetic abrasive finishing (MAF) is one of advanced finishing process which has special applications in medical equipment, dies, cutting tools , aerospace. This paper was focused on boron carbide (B4C) with iron powder which mixed together to perform finishing process into magnetic abrasive finishing . experiments show that boron carbide enhanced the surface roughness from ( 0.15-0.088) µm at  concentration 25% boron carbide and 75% iron powder ,mesh100, gap 1.5mm and the best value of surface roughness was 0.011µm while the concentration 33% boron carbide and 67% iron powder , mesh 200, gap 2mm otherwise the maximum value of metal removal rate obtained 0.0045 gm/min at concentration 25% boron carbide and 75% iron powder , mesh 100, gap 1.5mm.
