A review on Magnetic Abrasive Finishing Process for Finishing a Work piece Surface

Abstract

Magnetic abrasive finishing (MAF) process is a process that often occurs at the end of machining operations for the purpose of finishing the surface of the workpiece. MAF process uses the effect of the magnetic field to control the ferromagnetic abrasive powder. The powder usually consists of an iron (ferromagnetic) powder mixed with a high strength non-ferromagnetic powder, like tungsten carbide, and brass alloy. The non-ferromagnetic powder is used to increase the strength of the abrasive powder. In theMagnetic abrasive finishing process, six parameters are used: viscosity, doze (Quantity of the powder), the distance between the pole and the workpiece, pole diameter, pole rotational speed, and current.Each parameter has three levels of variance. In this paper, an attempt has been made to review and compare different methods for finishing the surface of the workpiece.
