Fine Finishing of Extended Surfaces of 316 L Stainless Steel Thin Plate with Magnetic Abrasives

Abstract

Some of the materials used in modern industries and industrial applications are difficult to finish with high degree of accuracy and minimal surface defects using conventional machining and polishing techniques. Stainless steel is one such widely used material that is ductile, tough and difficult to finish with traditional processes. This study aims to finish effectively the thin 316 L stainless steel plate using nontraditional technique as it is very difficult to finish using traditional technique. Response Surface Methodology approach for experimental design (Box-Behnken) is used for performing and analyzing the experimental work. Box-Behnken design is having the maximum efficiency for an experiment involving three factors and three levels. The experimental results indicate that the 316L stainless steel plate can be successfully finished with diamond sintered magnetic abrasives. The process yields best results of Rotational Speed = 200RPM, Feed = 40mm/sec and Machining Time = 60minutes for PISF. The PISF was improved by 45%.
