“…When magnetic field is applied on these MAPs, they form a chainlike structure whose strength and stiffness depend on the applied magnetic flux density [4,5]. Aluminum oxide (Al 2 O 3 for soft material) and silicon carbide (SiC for hard material) have been used as the most common abrasive particles [6][7][8]. These MAPs may be used in bonded or unbounded form.…”

Surface finish is one of the important parameters that affects functional aspects of an assembly like friction between mating parts and wear resistance. Magnetic abrasive finishing is one of the advanced finishing processes which has the ability to produce nano-finished surface by removing material in the form of microchips. The present paper introduces a novel tool based on magnetic abrasive finishing (MAF) principle for polishing holes, blind holes, grooves, and vertical surfaces. The tool designed and developed in the present study consists of two permanent magnets with their similar pole facing each other, such that a high magnetic flux density is achieved around the circumferential area between the magnets and the same has been simulated using Maxwell software. In order to evaluate the performance of the tool, experimentation based on central composite design (CCD) technique was performed to finish stainless steel (SS304) pipe. The results so obtained were analyzed to study the effect of process parameters like rotational speed, magnetic flux density, abrasive size, and abrasive weight percentage on percentage change in surface roughness. The analysis showed that the magnetic flux density was the most effective parameter while finishing the stainless steel (SS304) pipe followed by rotational speed. Experimentation at an optimized condition resulted in a surface finish of 56 nm. Further SEM images were taken to understand the surface morphology of finished surface.

“…They found that the percentage change in surface roughness (%ΔRa) is influenced by abrasive particles mesh size followed by percentage weight of abrasive particles, electromagnet rotations per minute, and applied voltage during finishing of AISI 52100 steel using MAF process [15]. Kala and Pandey [16] measured finishing force and torque during double disk magnetic abrasive finishing process. The normal finishing force is significantly affected by lower and upper working gap as well as finishing torque [16].…”

Finishing is the final operation during manufacturing process of a component. It is time consuming, difficult, and usually a costly operation. Finishing cost can be as high as 15 % of the total production cost. Magnetic Abrasive Finishing (MAF) is an advanced finishing process in which a mixture of non-ferromagnetic abrasive particles and ferromagnetic carbonyl iron particles (CIPs) is used to do finishing operation with the aid of magnetic force. The iron particles form a flexible chain matrix in which the abrasive particles are trapped in between or within the chains. This is called flexible magnetic abrasive brush (FMAB), which when given a relative motion against a (metal/non-metal) surface, it finishes the surface. The present work deals with the effect of the process parameters such as applied magnetic field, concentration of abrasive particles and iron particles in FMAB, and rotational speed of magnet on the finishing forces that are generated during vertical MAF of ferromagnetic (EN-8) and nonferromagnetic material (brass) flat workpieces. Empirical models for force prediction have been developed based on the experimental results. Effect of the applied magnetic field is seen to have the most significant contribution among all the input parameters. Percentage of oil in FMAB is not a significant factor for normal force, but it is a significant factor to the tangential force. The tangential force increases up to 3 % of oil content in FMAB, and it starts decreasing in the range of 3 to 5 % oil content.
