With technological developments, new metals and alloys are being developed to meet the industrial demands. Inconel 625 is one such nickel based alloy, which has excellent materialistic properties. Due to its superior properties, it has become the choice of nuclear industries, marine applications, solar power stations, heat exchanger tubing etc. But, machining and finishing of this alloy is difficult task with conventional methods. In present research work, Magnetic abrasive finishing has been implemented to improve the surface finish of flat Inconel 625 surfaces. The main parameters considered in present work are: process¬ing time, weight %age of abrasive and pole rotational speed. Effect of process parameters on the percentage improvement in surface finish (PISF) has been analyzed. For experimentation design, Response Surface Methodology is used and experimental results have been analyzed using ANOVA. The results indicate that Magnetic abrasive finishing can be successfully implemented to finish the flat Inconel 625 work piece and parameters like processing time, pole rotational speed and Wt. % of abrasives have significant effect on PISF.
