The smoother surface is the first requirement in the field of metal cutting and fitting industries at present time and this requirement cannot be approachable with conventional finishing processes. Magnetic abrasive finishing is a modern approach to match our current requirements of surface finishing in metal part production industries. The value of surface finish is more important in the fields of petroleum, medical, electronics and lubrication industries. Electromagnetic abrasive finishing is a machining process in which the surface of the work piece is grinded by removing the material as micro-chips by abrasive particles mixed and suitable size of iron particles in the presence of magnetic field. To improve the surface quality of machined parts many other methods has been used earlier for better finishing but it did not produce much fine surface. To obtain a good finished surface a new method has been exercised which is known as electromagnetic abrasive finishing. This process has been developed for a wide variety of application including the manufacturing of components in the field of medical, fluid systems, optics, dies and molds, electronic, micro electro mechanical systems. Many mechanical as well as electrical researchers had worked to get better surface finish on magnetic abrasive machining w.r.t. different machining parameters like work rotation speed, standoff distance, concentration of mixture of powder and machining time. It is well known that magnetic flux density and work rotation speed has a great impact on surface finish. The much work has not been done on the mechanical parameters related with this machining process. Mixture contains iron particles (Fe particles 50 microns) and abrasive particles (Al2O3) of different mesh size. It has been observed that the increase in rotational speed, weight of abrasive and their size (iron particles and abrasive particles) improve the surface finish. So an experiment has been carried out to find out the optimum value of mechanical parameters at which better finishing can be achieved. In the present work, magnetic flux density is created by using the electromagnets. Magnetic abrasives mixtures were prepared by mixing ferromagnetic powder and abrasive powder. Brass, Cast Iron and SS-305 pipes have been used as work pieces. To find the optimum values of mechanical parameters a set-up is designed in which a lathe machine chuck is used as a work holding device and to rotate the work piece. Two electromagnets are arranged opposite to each other to create the magnetic force. Work piece is kept between these electromagnets.
