Paper Abstract

According to Preston equation, mathematics model of magnetorheological finishing (MRF) is established in this paper. We analyze the pressure acting on workpiece of this model, and find out that the pressure consists of hydrodynamic pressure and magnetization pressure. At same time, the magnetic field used in magnetorheological finishing is introduced, and the expression of intensity of this magnetic field is given. A MRF example for convex spherical surface workpiece in this magnetic field is presented, the mathematical expression of the pressure is deduced, and the rationality of the mathematical expression of the pressure and the reliability of the mathematics model is verified by experiment. Based on mathematics model of magnetorheological finishing and experiment, the curves and the laws of the effect on magnetorheological finishing by several parameters are given.
