Surface quality is one of the most important properties of the precision devices. Poor surface quality of engineering products results in various problems during operations, such as malfunctioning, excessive wear, geometric inaccuracy, etc. The surface quality of a product is mostly determined during the manufacturing process. The traditional fishing process does not offer a flexible, cost effective option for finishing small precision devices. Magnetorheological fluid assisted finishing processes are one such kind of finishing processes, which has greater flexibility towards process control and one can finish with close tolerances and without damaging surface topography. Hence, this paper gives the review of abrasive flow finishing, magnetorheological finishing(MRF), Magnetorheological jet finishing (MR Jet,)magnetorheological abrasive flow finishing(MRAFF), Magnetorhological honing(MRAH), and Ball end Magnetorheological Finishing( Ball end MRF), . This article provides a comprehensive literature review of Magnetorheological finishing process in terms experimental investigation, and rheological characterization of Magnetorheological fluid. This article deals with various advancements in MRF process and its allied processes have been discussed.

Keywords: Precision finishing, Magnetorheologcal fluid, Magnetorheological finishing processes.
