Abstract

A magnetic abrasive finishing process using an alternating magnetic field is proposed for the finishing of complex surfaces. In an alternating field, the periodic changes in current will cause the magnetic cluster used as a magnetic brush to fluctuate, which will not only continuously replace the abrasive particles in contact with the workpiece, but also periodically adjust the shape of the magnetic cluster to better fit the surface of the workpiece. In this paper, the influence of a combination of alternating and static magnetic fields on the magnetic field in the finishing area is analyzed. The feasibility of this process for finishing micro-grooves is investigated. Simulations and experimental measurements show that the combination of alternating and static magnetic fields can retain the advantages of the alternating field while increasing the magnetic flux density in the finishing area. The experimental results show that the process is feasible for finishing micro-grooves, with an excellent deburring effect on the groove edges.

利用交变磁场对微沟槽进行磁磨料精加工的应用研究

针对复杂表面的精加工，提出了一种利用交变磁场的磁性磨料精加工工艺。在交变场中，电流的周期性变化会导致用作磁刷的磁簇发生波动，这不仅会持续替换与工件接触的磨料颗粒，还会周期性地调整磁簇的形状，以更好地贴合工件表面。本文分析了交变磁场和静态磁场的组合对精加工区磁场的影响。研究了该工艺在微细槽加工中的可行性。仿真和实验测量表明，交变磁场和静态磁场的结合可以保持交变磁场的优势，同时提高精加工区域的磁通密度。实验结果表明，该工艺对微细槽的精加工是可行的，对槽边缘具有良好的去毛刺效果。
