Abrasive flow machining (AFM): An Overview

 · Abrasive Flow Machining (AFM) was developed in 1960s as a method to deburr, polish, and radius difficult to reach surfaces like intricate geometries and edges by flowing a abrasive laden viscoelastic polymer over them. Based on the application, three different types of machines have been reported i.e, one way AFM, two way AFM and orbital AFM.
