Effect of Magnetic Pole Orientation on Viscoelastic Magnetic Abrasive Finishing Process

Abstract

The advancement of material technology has created a need for new methods and technology which can provide a better Machining and finishing process. Viscoelastic magnetic Abrasive Finishing is a new method which has evolved from traditional MAF process where there is a use of abrasive-Ferromagnetic laden media which provide an effective machining option. In this process, Ferromagnetic particles, along with abrasive particles in presence of viscoelastic medium provide better surface finish as viscoelastic medium increases the bonding of ferromagnetic particles with abrasive particles. In the present paper Ansys Maxwell 16.0 is used to obtain the distribution of magnetic field on the workpiece through which the effect on machined surface can be predicted. The pattern is obtained using combination of 6 magnetic poles taken 2, 3 and 6 at a time by arranging them at different angles. After observing the pattern, it was found that the most effective machining would be done by taking 6 poles, surrounding the workpiece as it would cover the entire surface of the workpiece and the combination of 3 magnet at an angle of 60° is effective when 3 poles are taken at a time.
