Abstract: Extrusion Honing (EH) is also known as Abrasive flow machining (AFM) is a fine finishing process mainly applicable for difficult to reach internal surfaces and components with intricate geometries finished through the action of extrusion, where abrading action of the polymer media laden with abrasive particles machines the component surface. The EH processes is an advanced finishing techniques widely used as finishing machining process a solution to produce parts with high surface properties that mainly used in high-end industries like aerospace, automobile, medical, tool and die, and prosthetic. EH processes is mainly used for finishing operations namely polishing, de-burring, removal of cast layers, radiusing and finishing of intricate shapes by flowing abrasive laden viscoelastic media over the surfaces to be finished. Although EH have a wide range of applications and could be used in every shop floor as a finishing solution, their usage is limited owing to high initial and running costs associated with them. In this work, the experiment is conducted using a one way extrusion honing machine and the process is carried out on Nickel Alloy A-286 specimens, a super alloy having high hardness and high strength properties which is machined to get good surface finishing. In this paper a thorough research is done on how the EH parameters impacts on surface parameters of Nickel Alloy A-286. The results obtained are measured and extruded surface is analysed with the help of surface roughness measuring instrument.
