Abstract: Applications of finished pieces have been increased by developing of industry. But finishing of some pieces such as the tubes with special shapes is impossible by common methods like grinding. In magnetic abrasive finishing (MAF), the chipping force is controlled by the magnetic field. Using this method, we can get high quality finishing close to nanometre on plane surfaces and internal or external surface of the tubes. MAF can finish the magnetic and non-magnetic materials such as aluminium and corrosion-resistant steel. This paper offers a new and an efficient method for internal finishing of curved tubes. We have discussed the influences of piece material, abrasive material, poling and weight of abrasive material on finishing quality using the design of experiments. The results show that copper has the best surface quality and the most chipping rate.
