Various developments in Abrasive Flow Machining Process: A Review

Abstract

Abrasive flow machining is a nonconventional process used for polishing of metallic components, internal inaccessible cavities or recesses using a semi liquid paste. It was developed to deburr, polish the surfaces having complex geometries and edges by flowing abrasive particles with a visco-elastic nonconductive media over them. Abrasive particle sharp cutting edges remove the material by abrasion mechanism from the workpiece surface. In the recent year, work has been carryout towards the development of abrasive flow machining for achieving the higher material removal and improved surface finish. This method has a unique property of simultaneous improvement in material removal and surface finish. In this paper authors discussed about various recent developments in abrasive flow machining with major objective of improving the productivity of the process.
