C. Jayswal b a,b Mechanical Engineering Department, Madan Mohan Malaviya University of Technology, Gorakhpur 273010 Uttar Pradesh, India Abstract Abrasive flow finishing (AFF) is used to radius, polish, deburr and confiscate recast layer of components in an extensive variety of components. Surface finishing achieved by flowing a semi-viscous media through the target surface for finishing. There is a need for economic media because commercial media cost is too high (Rs2.5 lakhs/kg), available only in three standard forms and supplied by only one company (Extrude Hone Corporation). So, the researchers developed alternate media at low cost, easy availability. In this article, various types of media discussed from the past works have done by researchers. The selection of media depends on various testing as thermogravimetric analysis, flow capability, mechanical and rheological properties. Effective media prepared by mixing abrasive particles, binding materials and hydrocarbon oil in a fixed proportion, usually abrasive particles and binding materials ratios vary between 1:4 to 4:1 depends on the processes. The performance of the media calculated by its finishing property on an AFM and various hybrid setup. This review provides a vision into the various media in AFM and creates an improved understanding of finishing processes, to help in the selection of optimal machining limitations for the surface finishing of wide-ranging workpieces in practice. © 2019 Elsevier Ltd.

Introduction Abrasive Flow Machining is a process in which the desired level of surface finishing achieved by flowing a semisolid media across the workpiece. The major key role of AFM and its hybrid processes is abrasive media, which is a mixture of abrasive particles, binding materials and hydrocarbon oils in a definite proportion. The presence of working fluid in the duos interface significantly increased frictional forces and decreases abrasive tool wear * Corresponding author. E-mail address: pawankumar_rsme@mmmut.ac.in
