PREDICTION OF SURFACE ROUGHNESS AND METAL REMOVAL RATE INTO MAGNETIC ABRASIVE FINISHING FOR SILICON CARBIDE ABRASIVE
Abstract
Magnetic abrasive finishing (MAF) is one of advanced method which play a major role in important applications ( medical, rocket and aerospace parts , dies) .this paper was focused intoprediction of surface roughness and metal removal rate during intervening important parameters (mesh size ,concentration,gap between workpiece and poles).experiments show thatthe best surface roughness can be obtained when machining workpiece of low carbon steel by silicon carbide (Sic) was 0.007µm at concentration 33% SiC and maximum metal removal rate can be obtained 0.004gm at concentration ( 25% SiC and 75% Fe) the Minitab software version 17 was used to predict the surface roughness and metal removal rate which obtained good result and agreement with experimental values for surface roughness and metal removal rate when comparing between them reach to 98.66%.
