Modern advance finishing process in machining Process also having qualified reduction of tool resistance condition limitations i.e. in EDM, ECM, USM, AJM etc. cutting edge relative motion with Pre distinct motion and respect to the work piece surface be the foremost restraint during machining multifaceted shapes. For that avoid the restriction little various cutting edges in a few insecurely bonded from be heading for multifaceted Shapes to be machine. But due to the lack of control over the finishing forces, these possess the limitation for finishing complex geometry and moreover sometimes these processes communicate surface and subsurface damages. Many advanced finishing processes have been established to challenge these issues. Magnetorheological fluid aided finishing processes are one such kind of finishing processes, which has greater flexibility towards process control and one can finish by required tolerances among without destructive surface profile.
