Study in MAF of AISI304 Material Using Grey Relational Analysis

Abstract:

The purpose of this study was using a new approach of grey relational analysis based on Taguchi experimental design to employ the magnetic abrasive finishing (MAF) method to process the stainless AISI304 material on surface abrasive operations. The operations were demonstrated in the permanent magnetic polishing mechanism, it was installed in the CNC machining center. The operations of the parameters such as magnetic field, pole revolution, feed rate, working gap, abrasive, and lubricant, were considered. The confirmation experiments showed the optimal operational condition of surface roughness. The collected data were analyzed using a new approach of grey relational analysis to establish of abrasive magnetic finishing parameter and quality characteristic. The optimal parameter condition to process the stainless AISI304 material was conducted using two stage processes; prior to the rough polishing, the Rmax value was equal to 2.572 μm, Rmax value was 0.10 μm after the finished polishing. It could be concluded that magnetic abrasive finishing was one of the excellent technologies of getting good surface roughness with high efficiency.
