The effectiveness of the magnetic abrasive finishing (MAF) process relies on several factors, including the brush's flexibility that varies across tools. This study aimed to optimize the results of five key parameters (voltage, finishing time, gap distance, rotating speed, and particle size) on surface roughness (SR) and microhardness (HV) using the grey relational analysis (GRA) method. Experimental work employed the Taguchi design with L27 trials in Minitab 17, involving five variables with three levels for each. The impact of these parameters on microhardness and surface roughness for stainless steel SUS420 bubble cups was assessed using Taguchi and regression analyses. The best roughness improvement and the most substantial enhancement in microhardness were individually obtained with the GRA method. This method assigned the best results for both surface roughness and microhardness. According to Taguchi analysis, the voltage parameter has the main or maximum parameter effect on grade, followed by gap distance, time, spindle speed, and particle size. It was found that the optimal parameters were the same as the input parameters.

“…The time is always adapted and important in any process. So, the main parameters that affect the qualitative productivity of this process are the finishing speed, time, the gap between the workpiece and the brush, magnetic flux density and the magnetic abrasive [10][11][12][13][14][15][16][17].…”

To improve the surface roughness of Copper-Nickel alloy (Cu-Ni alloy) and explore the effect of magnetic abrasive finishing on the surface hardness and hydrophobicity of Cu-Ni alloy, the spherical magnetic abrasives are prepared by atomizing rapid solidification method. The effects of various process parameters on the surface quality of Cu-Ni alloy are explored, and the optimal process parameters of magnetic abrasive finishing of Cu-Ni alloy are obtained. The Neodymium-Iron-Boron permanent magnetic pole is used to grind the workpiece with XK7136C CNC milling machine. Three dimensional profilometer, metallographic microscope, and digital Vickers hardness tester are used to analyze the surface morphology of the workpiece. The hydrophilicity and hydrophobicity of the workpiece are measured by a contact angle goniometer. The effects of spindle speed, feeding rate, processing distance, and abrasive filling amount on the surface quality of workpiece are investigated by the orthogonal experiment and the single factor test. When the spindle speed is 1300 r/min, the feeding rate is 13 mm/min, the processing distance is 1.2 mm, and the abrasive filling amount is 2.0 g, the surface roughness of Cu-Ni alloy decreases from 0.212 to 0.023 μm and the hardness increases from 114 to 119.8 hv. Finally, the mirror effect of Cu-Ni alloy is achieved. When the optimal test parameters are used, the surface roughness of Cu-Ni alloy can be effectively reduced in a short time. The surface quality of the workpiece is improved, the surface hardness of the workpiece is affected to a certain extent, and the service life of the workpiece is prolonged.

With the rapid development in the industry, applications of finished parts are increasing day by day. However, the surface finish of the parts fabricated by conventional processes could not readily meet the requirements of various applications. Therefore, post-processing is needed to further improve the surface quality. Magnetic abrasive machining uses a flexible magnetic abrasive brush to remove material from the workpiece surface at a controllable rate. This cutting tool sticks to the workpiece during finishing operation and exerts a small force on the surface. In magnetic abrasive machining, the cutting tool neither requires compensation nor dressing. In this paper, the internal finishing of aluminum pipes has been investigated in magnetic abrasive machining tests using silicon carbide-based glued magnetic abrasives. For evaluating the performance of these magnetic abrasives, experimental work according to the central composite design technique was carried out to finish the aluminum pipes. The results so obtained were analyzed to study the influence of process parameters like magnetic field strength, speed of workpiece, abrasive mesh size and quantity of magnetic abrasives on percentage improvement in surface finish and material removal rate. The analysis showed that magnetic field strength was the most effective parameter while finishing the aluminum pipe followed by the quantity of magnetic abrasives. The finishing at optimal condition resulted in a surface finish of 0.07 μm. Further, scanning electron microscopy of the surface before and after magnetic abrasive machining was taken to study the improvement in surface finish. HIGHLIGHTS Magnetic abrasive machining (MAM) of aluminum work specimens have been performed by SiC-based magnetic abrasives The central composite design has been used for planning and execution of experiments The surface finish and material removal rate of the machined work specimens have been analysed as a performance measure of MAM process The high value of improvement in surface finish and material removal rate at optimum machining conditions have been observed Scanning electron microscopy (SEM) has been employed to study the surface topography of machined surfaces GRAPHICAL ABSTRACT
