Abstract
Magnetorheological finishing (MRF) is a novel precision optical machining technology. Owing to its flexible finishing process, SlRF can eliminate the surface and subsurface damage, improve the surface quality and correct surface figure errors. The finishing process can be easily controlled by a computer. Through proper designing of numerical control, spheric and aspheric optics can be machined by MRF with high quality. The surface shape correcting was achieved using dwell time algorithm melhod, optical sphere workpiece was machined using this method and the surface shape error value of 2 point peak-valley was improved from 0.17 μm to 0.07 μm.
