Abstract

Magnetorheological finishing (MRF) is a deterministic optical element polishing method that achieves material removal by means of the sheared and rheo-logical behavior of magnetorheological fluids. To realize high precision fabrication of large-aperture optical components, MRF technology had been explored in this paper. The main factors affecting the removal efficiency were investigated by orthogonal experiment. It indicated that the influence of the immersion depth and the thickness of ribbon on removal efficiency was more remarkable than the other parameters. The process of MRF machining component is established. Finally, the 590mm × 400mm plane optical element are manufactured using the MRF, and the result are very good.
