Vaishya Journal on Material Science 2347–615X 1 3 22 28 AFM (Abrasive Flow Machining, CFG, RPM, Surface Roughness, Taguchi Method, ANOVA In the present era, modern manufacturing processes are hybridized with conventional and non-conventional processes to obtain better results. AFM is a widely used non conventional machining process for smoothening of rough edge inside the work piece by flow of an abrasive medium. The abrasive particles in abrasive media remove the excess material from surface and produce finished surface. Centrifugal force assisted abrasive flow machining process is a new hybrid non-traditional machining process that is developed as a technique for better finishing of surface as compared to simple AFM. In this study, an attempt was made to depict the effect of different process parameters on percentage change in roughness value. The parameters are type of material, abrasive particle size, rotational speed of rod inside the workpiece and axial pressure, to see their effect on percentage change in surface roughness. Taguchi technique was considered for experimental design without taking any interaction. The unit has been designed to satisfy the basic requirement of hybrid AFM i.e. by attaching a rod inside fixture by gear arrangement having rotational mechanism in set-up. For experimental design and analysis of different parameters, L orthogonal array based upon taguchi method 9 was used. October - December 2013 Copyright © 2013 i-manager publications.
