COMPUTATIONAL AND EXPERIMENTAL STUDY OF CNT PARTICLES BASED ABRASIVE MEDIA USED IN ABRASIVE FLOW MACHINING FOR ALUMINIUM WORKPIECE

Abstract

Abrasive Flow machining (AFM) is a fine finishing process for internal inaccessible cavities or recesses. It employs an abrasives laden semi-solid media, which is selfdeforming and can finish the complex cavities under a hydraulic pressure. This method has a unique property of simultaneous improvement in material removal and surface finish. During the fine finishing of components using Abrasive flow Machining there is a important role of pressure distribution, velocity and temperature distribution at different points in Abrasive Flow Machining. To improve the efficiency of the process, it is very important to know the critical parameter. A three dimensional model of Abrasive flow machining was developed to analyze the effect of parameters (Pressure, Velocity, Temperature) by using Ansys 14 and Fluent software. Abrasive flow Machining has a limitation of low material removal. To minimize this limitation an experiment has been conducted by using (carbon nano tube)CNT as abrasive along with Al2O3 in the AFM to get more material removal and better surface quality
