The Impact of Magnetic Abrasive Finishing (MAF) Process Parameters on the Microhardness of Stainless Steel SUS420 Bubble Cups

Abstract

improve microhardness (MH) most are, in order, gap distance, voltage, time, p article size, and spindle speed. The percentage change in microhardness (%∆MH) increases with higher voltage and time values and decreases with higher particle size and spindle speed values. This study observes an exception to this trend for the gap distance value of 1.2 mm. The use of smaller particle sizes in the range of (20-63) µm showed the most significant enhancement in microhardness (MH) at 21.20%, whereas larger particle sizes (125-250 µm) exhibited lower enhancement in microhardness (MH) at 4.12%.
