“…Wang and Hu [15] stated that the material removal rate of H62 brass is highest among the other work materials, i.e., 316L stainless steel and Ly12 aluminum alloy. Singh et al [16] have compared the various magnetic abrasive manufacturing methods and concluded that sintered magnetic abrasives give the highest improvement in the surface finishing of most of the materials.…”

This article deals with the optimization of process parameters involving in the magnetic abrasive finishing (MAF) process to achieve the optimum responses. In order to choose to the best decisive course of action, we have used the weighted aggregated sum product assessment (WASPAS) method. This method is a multi-criteria decision-making process; here, it optimizes the six process parameters of the MAF process. The WASPAS is used to find the optimum parametric setting of the process parameter for the combined effect of the output responses, i.e., percentage improvement in surface finish (PISF) and material removal rate (MRR) in terms of total relative importance index Q i. The process parameters are namely rotational speed, working gap, particle size of abrasive, quantity of abrasive, finishing time and magnetic flux density, and responses are PISF and MRR. The analysis of variance is implemented not only to find out the percentage contribution of each of the process parameters but also to know the effect of interaction between any two process parameters. Finally, a regression equation is developed as per the backward propagation method and the predicted values are estimated from the equation. Those values are further compared with the experimental values.

“…The particles produced from this technique are moulded at high pressure and high temperature inside an inert gas environment. The subsequent compacts are then crushed and sieved into a particular particle size [6,7]. The crushing of compacts brought about the irregular shape of MAP and the improvement of surface finish quality was limited because of the nonuniform depth of cut.…”

Magnetic abrasive flow finishing (MAFF) is an unconventional process capable of producing fine finishing with machining forces controlled by a magnetic field. This process can be utilized for hard to achieve inner surfaces through the activity of extrusion pressure, combined with abrasion activity of a magnetic abrasive powder (MAP) in a polymeric medium. MAP is the key component in securing systematic removal of material and a decent surface finish in MAFF. The research background disclosed various methods such as sintering, adhesive based, mechanical alloying, plasma based, chemical, etc. for the production of bonded MAP. This investigation proposes bonded MAP produced by mechanical alloying followed by heat treatment. The experiments have been conducted on aluminum tubes to investigate the influence of different parameters like magnetic field density, extrusion pressure and number of working cycles. The bonded magnetic abrasive powder used in MAFF is very effective to finish tubes’ inner surfaces and finishing is significantly improved after processing.

“…They also concluded that stock removal and surface roughness improvement can be remarkably improved by adding the machining fluid (such as stearic acid, straight oil type of grinding fluid) to unbounded MAPs. Singh et al [2] analyzed the performance of flexible magnetic brush and identified four parameters which magnetic field intensity (by varying current to the electromagnet), space between the work piece and magnetic poles, abrasive grain size (mesh number) and number of cycles. They conducted a number of experiments and used RSM and ANOVA and lead to the conclusion that magnetic flux density which depends upon the current to the electromagnet and machining gap is the main parameter followed by mesh number and number of cycles.…”

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%.
