Abstract

<p>In order to achieve the finishing of micro complex surface, a magnetic abrasive finishing process using an alternating magnetic field is proposed. In the alternating magnetic field, the periodic change of the current will cause the magnetic cluster to fluctuate up and down, which can not only continuously mix and update the abrasive particles, but also periodically adjust the shape of the magnetic cluster to better fit the surface of the workpiece. In this paper, the influence of the combination of alternating magnetic field and static magnetic field on the magnetic field and magnetic cluster is analyzed. The feasibility of this method for finishing micro complex surface is investigated. Through the observation of magnetic cluster, it is found that in the combined magnetic field, the fluctuation amplitude of magnetic cluster increases. At the same time, through the measurement of magnetic flux density, the combined use of alternating magnetic field and static magnetic field increases the magnetic flux density in the finishing area. The experimental results show that this method has the feasibility of finishing micro complex surface and has deburring effect.</p>
