磁気援用研磨に関する研究 (第2報): 研磨量分布に与える磁場分布の影響

This paper describes the effect of the magnetic field distribution on the removal distribution of the workpiece surface in the magnetic field-assisted polishing method. In case of applying this method to the curved (aspheric) surface polishing, the next process is suitable. The designed shapes are first generated precisely by turning or grinding, and then the surfaces are finished only to improve the smoothness, with the previous form accuracy being maintained. Therefore, in order to carry out the uniform removal polishing using the magnetic field-assisted polishing, it is important to clarify the processing mechanism of this polishing method. In this report the relation between the distribution of magnetic field and the polishing pressure distribution was analyzed theoretically and experimentally using several shapes of magnetic poles in the polishing set-up. And, by polishing examination of the flat glass, the relations between the magnetic field distribution, polishing pressure distribution and polishing removal distribution were analyzed experimentally. As a result, the relations between the magnetic field distribution, polishing pressure distribution and polishing removal distribution were clarified
