Abstract

A new planarization technique with an instantaneous tiny-grinding wheel cluster that is based on the magnetorheological (MR) effect is presented in this paper. The B-H curve of the MR polishing fluid is calculated, and the results show that the B-H curve is nearly linear and its relative magnetic permeability is about 2.63. Based on the above results, three designs of the polishing disc with the tiny-grinding wheel cluster are analyzed by using the electromagnetic field finite element simulation software. The simulation results show that the design where the magnetic poles are fixed alternately and contrarily to form a closed magnetic circuit has the optimum effect.
