“…Cheng et al (Cheng, Yam et al 2009) were introduced a novel design of polishing tool comprising of a self-rotating wheel and brass wire coils aligned to the direction of its rotating axis as shown in Fig 2. And also they presented an experimental study to determine the magnetic fluid viscosity as a function of the applied electric voltage through generation of magnetic field. They observed that viscosity would increase with the driving voltage.…”

In order to overcome the defects of conventional magnetorheological finishing (MRF) processes that are unable to finish small curvature radius concave surfaces of diameter within 10 mm, a novel precision MRF process using small ball-end permanent-magnet polishing head with a diameter of 4 mm is proposed in this paper. And experimental setup of a four-axis linkage MRF machine tool is fabricated. Magnetostatic simulation of the distribution of magnetic flux density indicates that the magnetic field uniformity of produced polishing head is 93.3 %. Magnetizing force analysis is done to analyze the formation of magnetorheological fluid in finishing region. In addition, the suitable range of C-axis angular position for finishing is generated to be 60°~70°. Finishing experiments on both nonmetallic and metallic specimens with different surface shapes have been conducted. The ability of the developed method of finishing process to improve surface characteristics of a workpiece is demonstrated to reach the surface roughness of finished surfaces below Ra 6 nm. It confirms that the present MRF process is capable of improving surface quality and performing the nanofinishing on small curvature radius concave surfaces.

Magnetorheological (MR) finishing is a smart finishing processes applied to a variety of applications. In the present work, an attempt has been made to improve the percentage reduction in surface roughness with sintered magnetic abrasives based MRP fluid on BEMRF tool. Sintered magnetic abrasives were developed by mixing of 20 vol% carbonyl iron powder (CIP) CS grade and 25 vol% SiC in ball mill then pellets of 5 g each have been made at 8 ton pressure. These pellets were allowed to sinter in tubular furnace at 1200°C in the controlled atmosphere of argon. The sintered pellets were crushed in a ball mill to obtain sintered magnetic abrasives. The morphology and magnetizability of sintered magnetic abrasives have been studied with scanning electron microscope (SEM) and vibration sample magnetometer (VSM). MRP fluid was synthesized with 45 vol% sintered magnetic abrasives and 55 vol% base fluid. Experiments were conducted on mild steel work-piece for 30 min using BEMRF tool at given machining conditions. Percentage reduction in surface roughness (%ΔR a ) was calculated and compared with %ΔR a obtained by finishing mild steel work-piece with unbonded magnetic abrasives based MRP fluid and found better results. The effect of rotation per minute (RPM) on %ΔR a has been studied and found optimum by conducting the experiments at higher values of RPM keeping other machining conditions same. The experimental study shows that the sintered magnetic abrasives based MRP fluid in MR finishing may be used at higher rotational speeds without tool aging effect and impart a higher finishing force on the workpiece surface, improves finishing capability of the process.
