With progressions in technological advancements, new materials are being developed to meet industrial requirements. One such Nickel based super alloy is Inconel 625. Inconel 625 exhibits extraordinary mechanical properties along with chemical stability at high temperature. Due to extraordinary mechanical, physical and chemical properties, Inconel 625 is exceptionally hard to machine/finish. In this book, magnetic abrasive finishing process has been proposed to finish flat Inconel 625 surfaces. Three different parameters processing time, pole rotational speed and weight percentage of abrasives and their range has been selected. Design expert software has been used to plan experiments. Seventeen experiments were conducted as per experimental plan. The effect of process parameters on output characteristics (Percentage improvement in surface finish and Material removed) has been analyzed. Microscopic analysis and SEM analysis of few work pieces has been also provided to analyze the effect of process parameters.
