“…It was perceived that slightly bonded particles may create a uniform flexible magnetic abrasive brush with a favorable motion of particles within the brush, thereby resulting in a smoother surface without imparting any further skewedness into surface. It was reported by Guo et al [9] that, upon keeping other process variables constant in MAF, SiC and coarse abrasives show higher material removal rate (MRR) than Al 2 O 3 and fine abrasives, meaning that SiC with larger abrasives reduces surface roughness significantly. They also highlighted a slight discrepancy in the force data, indicating that finer abrasives cause higher force, which is not the case in the micro-cutting of material.…”

“…Such a conclusion is often imperatively stressed elsewhere in literature [23]. While surface roughness is considered a widely accepted performance indictor when the quality of surface is concerned, a more microscopic observation underpinning the material removal mechanism and surface damages, i.e., micro/nano cracks, fractures, and scratches, must be investigated to provide a holistic and informed quality evaluation of MAF [9]. In other words, a future mathematical model may need to take those perspectives into account to solicit the quality prediction.…”

“…This further necessitates investigating and confirming the efficacy of unboned particles. Furthermore, regardless of bonded/unbonded particles, the effect of abrasive type and geometry on finishing was shown to vary [9]. Often, mathematical modeling and optimization approach are employed to obtain the best set of parameters [10,11].…”

This paper investigates the underlying interplay between the key process parameters of magnetic abrasive finishing (MAF) in improving surface quality. The five process parameters considered were the working gap, rotational speed, feed rate, abrasive amount, and abrasive mesh when MAFed independently with two abrasive particles—SiC and Al2O3. A series of experiments were conducted with an in-house built MAF tool. Based on the main effect results, a model predicting roughness reduction was developed. Results show that surface quality improvement and the underlying dominant process parameters seem unique to the abrasive type used. When MAFed with SiC, the abrasive quantity and rotational speed influence the most. On the other hand, when MAFed with Al2O3, the trend is different to SiC, i.e., the abrasive mesh size and the working gap are dominant. The prediction model was well validated by independent experiments, indicating its accuracy in estimating and optimizing the process outcome. MAF is a simple process with a complex interplay between parameters. This is very crucial when abrasive type, size, and amount to be used are concerned, which warrants a deeper investigation in terms of underlying dynamics, interactions, and the deformation of abrasive, magnetic, and workpiece materials.

“…The technological reduction of internal thread surface roughness Ra < 1.6 μm during tapping is inseparably associated to the improvement of the condition of cutting tool teeth contact surfaces that can be effected by performing finishing operations. Magnetic-abrasive finishing (MAF) [6,7] is a promising method of forming various conditions (rounding radius, roughness and microhardness) of tooth contact surfaces of a thread tap.…”

This article deals with the subject of using iron and titanium carbide (Fe + TiC) based composite powder for treatment of cutting tools in a magnetic field with the purpose of improving internal thread cutting process. As a result of studies performed by us, it has been established that composite powder grain size influences the condition of the contact surfaces of cutting tool teeth and process efficiency. Also a relationship has been discovered between the changes in internal thread roughness and the condition of thread tap teeth contact surfaces pretreated in a magnetic field by Fe + TiC composite powder having various grain sizes.

“…The most well-known is arguably the Magnetorheological Finishing (MRF) process, which is commercially available for superfinishing of high-value optics components [1]. Other MFAF processes include the magnetic abrasive finishing (MAF) process [2], an apparatus for finishing of ground glass edge [3], a double-magnet configuration for high material removal rate [4,5] that can also be mounted on a robotic arm [6], an apparatus for finishing of internal surface of tubes [7], an apparatus for finishing of micropore X-ray focusing mirrors [8], and a ball-end tool [9].…”

Magnetic field assisted finishing (MFAF) is a category of non-conventional finishing processes that use magnetic field to manipulate finishing media typically consisting of magnetic particles and non-magnetic abrasives suspended in a carrier fluid. In order to better control the process, an improved understanding of the actual removal process is needed. This paper will introduce a new material removal rate model for magnetic fieldassisted finishing (MFAF) that will aim do so. The model considers the complexity of finishing media used in MFAF processes, where two different types of particles are presented and interact with each other. The proposed material removal rate expression is based on contact mechanics and is a function of the number of active magnetic particles, number of active abrasives, force per magnetic particle, and force per abrasive. Expressions for particle numbers have been developed by considering an ideal facecentred cubic configuration for the magnetic particle network, while expressions for forces have been developed based on a proposed framework for the particle interactions. The model has been verified experimentally for a double-magnet MFAF process by varying the abrasive size and abrasive concentration. When the abrasive size was increased from 0.6 μm to 15 μm, the material removal rate decreased which is consistent 2 with the theoretical trend given by the model. Then, when abrasive concentration, given by the abrasives-to-carbonyl-iron volumetric ratio, was increased from 0 to 0.768, the material removal rate initially increased and then reached a maximum when the volume ratio is 0.259 before decreasing with further increase of the volume ratio. This is also in agreement with the theoretical trend given by the model.
