“…Apart from rotary motion of the cylindrical workpiece, axial vibratory motion is also introduced in the magnetic field by the oscillating motion of the magnetic poles or the workpiece to accomplish surface and edge finishing at a faster rate and with a better quality (Komanduri, 1996;Fox et al, 1994;Shinmura, 1999, 2004). The process is highly efficient, and the material removal rate and finishing rate depend on the workpiece circumferential speed, magnetic flux density, working gap, workpiece material properties, and size, type and volume fraction of abrasives.…”

“…Deburring of grinding burrs can easily be performed with this process. Fox et al [10] have found that unbonded MAPs yield a higher material removal rate (MRR) and bonded MAPs give a better surface roughness. The surface roughness value (Ra) of a ground rod after MAF has been achieved as low as 10 nm.…”

Magnetic abrasive finishing (MAF) is one of the advanced finishing processes, which produces a high level of surface quality and is primarily controlled by a magnetic field. In MAF, the workpiece is kept between the two poles of a magnet. The working gap between the workpiece and the magnet is filled with magnetic abrasive particles. A magnetic abrasive flexible brush (MAFB) is formed, acting as a multipoint cutting tool, due to the effect of the magnetic field in the working gap. This paper deals with the theoretical investigations of the MAF process. A finite element model of the process is developed to evaluate the distribution of magnetic forces on the workpiece surface. The MAF process removes a very small amount of material by indentation and rotation of magnetic abrasive particles in the circular tracks. A theoretical model for material removal and surface roughness is also proposed accounting for microcutting by considering a uniform surface profile without statistical distribution. Numerical experiments are carried out by providing different routes of intermittent motion to the tool. The simulation results are verified by comparing them with the experimental results available in the literature.

“…Kim [4] has developed the new type of magnetic abrasives composed of WC/Co sintered powder for the production of cleaning tubes, and found the optimal finishing characteristics. Fox et al [5] have found that unbounded magnetic abrasive particle (UMAP) yield higher material removal rate (MRR) and bounded MAP gives better surface roughness. Surface roughness value (R a ) of a ground rod has been achieved as low as 10 nm.…”
