A Comprehensive Review on Magnetic Abrasive Finishing Process

Abstract

In the nanotechnology era, the need for products with high quality and surfaces with free-from damage has become an urgent necessity. Many components in the precision industries such as electronics, automobile, medical, and aviation require high surface finish to meet their functional requirements, such as, reducing fluid flow resistance, friction, optical losses and increase fatigue strength. However, the scale of such surface quality cannot be achieved by traditional finishing methods. To overcome these limitations, many advanced finishing processes have been developed such as abrasive flow finishing, magnetorheological fluid finishing, magnetic float polishing, and chemical mechanical polishing and magnetic abrasive finishing. Magnetic abrasive finishing (MAF) is one of advanced finishing processes which offers superior surface finish over conventional finishing processes, because of its self-adaptability to finish of different geometric shapes, its a gentle tool which does not impact workpiece surface, its capability to polish advanced engineering materials and its low cost. This article has been focused on MAF, as well as reviewing of advanced finishing processes. The recent researches and challenges of MAF have been discussed as well.
