Abstract

The processing stability and properties of magnetorheological polishing device (MPD) play a crucial role in the processing of optical materials. In this study, a novel MPD was developed to improve the processing stability and properties. The device uses free abrasives to assist in magnetorheological polishing, and completes the self-sharpening of the abrasives in flexible pad using a dynamic magnetic field. This paper presents the principles and structures design involved. The mechanical characteristics of main components and magnetic field characteristics of a Halbach array were analyzed. Based on the developed device, the stability is studied. The advantages of free abrasive assisted magnetorheological polishing method were investigated. The results indicate that the structural design of the main components is reasonable. A dynamic magnetic field device can achieve greater changes in magnetic field intensity and gradient with fewer magnets. It exhibits excellent magnetic field properties. The results obtained by marathon experiment under the same parameters are all distributed within 95 % confidence interval. The processing stability of the MPD was verified. The method can effectively improve the processing performance and has certain advantages. Compared with the traditional magnetorheological polishing method, the processing efficiency can be improved by more than 29.68 %.
