Magnetic abrasive finishing (MAF) was advanced method used to remove metal by magnet abrasive from work metal which has important applications in (medical,aerospace parts and dies) .this paper focused into the influence of abrasive of silicon carbide (SiC) into surface roughness and metal removal rate , other parameters were taken into consideration (gap between workpiece and poles ,mesh ,concentration ) experiments prove that the best surface roughness can be obtained when machining workpiece of low carbon steel by silicon carbide (Sic) was 0.007μm at concentration 33% Si and 67% Fe with gap 2mm , mesh size 200 and maximum metal removal rate can be obtained 0.004gm at concentration 25% Si and 75% Fe with gap 1.5mm,mesh size 100 while maximum value of surface roughness was 0.073μm at concentration 25 % Si and 75% Fe with gap 1.5mm, mesh size 100
