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 an abrasive laden visco-elastic polymer over them. Based on the application, three different types of machines have been reported i.e., one way AFM, two ways AFM and orbital AFM. Because of simplicity in analyzing the physics, analysis of AFM process always refers to two ways AFM. Abrasion occurs wherever the medium passes through the highly restrictive passage. The key components of AFM process are the machine, tooling and abrasive medium. Process input parameters such as extrusion pressure, number of cycles, grit composition and type; tooling and fixture designs have impact on AFM output responses. AFM is capable to produce surface finish (Ra) as well as 0.05 mm, debur holes as small as 0.2 mm and radius edges from0.025 mm to 1.5mm. AFM has wide range of applications in industries such as aerospace, medical, electronics, automotive, precision dies and moulds as a part of their manufacturing activities. To overcome some of the draw backs such as low finishing rate and inability to correct the form geometry, researchers have proposed various versions of AFM machines abbreviated as M-AFM, DBGAFF, CFAAFM, spiral polishing and R-AFF. It is more time consuming to finish only one component at a time, hence to improve productivity the mass production in abrasive flow machining is the best way.
