“…The magnetic abrasive tools consist of ferrous particles mixed with fine abrasive particles (diamond (PCD), aluminum oxide (Al 2 O 3 ), silicon carbide (SiC), cubic boron nitride (CBN), carbon nanotubes (CNTs), etc. ), and such particles are called ferromagnetic abrasive particles or Magnetic Abrasive Particles (MAPs) [40]. Park et al [41] used a mixture of 16 wt% diamond abrasive (1 µm) and 2 wt% CNT par- ticles (0.01-0.04 µm) to finish the surface of zirconia ceramic bars.…”

Recent developments in the engineering industry have created a demand for advanced materials with superior mechanical properties and high-quality surface finishes. Some of the conventional finishing methods such as lapping, grinding, honing, and polishing are now being replaced by non-conventional finishing processes. Magnetic Abrasive Finishing (MAF) is a non-conventional superfinishing process in which magnetic abrasive particles interact with a magnetic field in the finishing zone to remove materials to achieve very high surface finishing and deburring simultaneously. In this review paper, the working principles, processing parameters, and current limitations for the MAF process are examined via reviewing important work in the literature. Additionally, future developments of the MAF process are discussed.

“…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.…”

“…The formation of bonded MAPs requires sintering at high pressure and temperature within an inert gas atmosphere. Therefore, most of the researchers [7][8][9] have used unbounded MAPs. It has been found that a decrease in abrasive particle size resulted in better surface finish [10].…”

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.

“…For the aforementioned finishing challenges, abrasive flow machining (AFM) process is a suitable candidate. This non-traditional polishing process is also termed as abrasive flow finishing (AFF) process [2], mainly due to a small quantity of material removal during the fine finishing of metallic components. AFM or AFF process was originally identified for deburring and finishing critical hydraulic and fuel system components of aircraft in aerospace industries.…”

“…AFM or AFF process was originally identified for deburring and finishing critical hydraulic and fuel system components of aircraft in aerospace industries. It can polish anywhere that air, liquid or fuel flows [2]. In this process, a self-deforming abrasive laden semiliquid paste (made up of viscoelastic polymer, gel and abrasive particles) is extruded (by employing two vertically opposed hydraulic actuators) through a controlled passage over the surface to be polished.…”

Abrasive flow machining is a fine finishing process, mainly for the finishing of complex internal/external surfaces of metallic parts. Like most of the finishing processes, this process is also a slow process due to low material removal rate. Hybridization of abrasive flow machining process (AFM) with other non-conventional machining (NCM) processes is being explored in the recent times, so as to overcome the main limitation of low material removal in the AFM process and to satisfy the stringent finish/functional requirements. The present study is about the development of a novel hybrid of electrochemical machining (ECM) and abrasive flow machining (AFM), for the fine finishing of internal holes or prismatic recesses. The new process has been termed as electrochemical-aided abrasive flow machining (ECA 2 FM) process, and higher abrasion of the material was observed in this process due to the synergetic effect of ECM and AFM processes. Further in the present investigation, the various process parameters have been optimized for the response characteristic of material removal, based on Taguchi method and using standard L 27 orthogonal array (OA) for the plan of experimentation. Overall, the ECA 2 FM process has a very promising future in the industries in terms of its ability to finish fast even if the component is thin/delicate and made of hard alloys.
