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. For the magnetorheological processing optics, an experimental study of the magnetorheological processing force was carried out. It was obtained that the relationship between the process parameters and element forces in magnetorheological polishing .The process parameters in MRF are the rotation speed of the polishing wheel, the magnetic field strength, the liquid flow rate, and the immersion depth. For MRF-600 magnetorheological polishing machine with polishing wheel Φ300mm, the normal forces range from 2N to 32N.According to the fitting curve between the magnetic field and the normal forces, the force is 6 times larger than that under the zero magnetic field condition. At the same time, the polished spots were collected under different magnetic field intensity. The law of the removal rate of polishing spots was obtained.
