Magnetorheological Fluid Finishing of Soft Materials: A Critical Review

Abstract

Magnetorheological Finishing (MRF) is one of the precision finishing processes and recently commercialized method for finishing of various materials like optical glasses, metals, non-metals etc. This method utilizes a suspension consisting of a fluid carrier which can be water or oil, both magnetic and non-magnetic particles and stabilizing agents. Rheological behavior of this mixture of magnetorheological (MR) fluid with abrasives changes under the influence of magnetic field which in turn regulates the finishing forces during finishing processes. Present study critically reviews the MRF process used for achieving nano-level finishing of soft materials and the advancements made in this process

Experimental and theoretical investigation into surface roughness and residual stress using ball end magnetorheological finishing

“…Simulation of magnetic flux showed that the shape and size of the ball-end finishing spot varied with the working gap at particular magnetic current. Sharma (2019) critically reviewed MRF, MRAFF, CMMRF, BEMRF finishing process and concluded that BEMRF process is an effective process to obtain high level of surface finish on variety of work pieces. Sharma (2020) reviewed in detail the BEMRF process and concluded that this process can be effectively used for finishing of both magnetic and non-magnetic materials.…”
