Paper Abstract

Magnetorheological finishing (MRF) of a diamond turned poly(methymethacrylate) (PMMA) flat was demonstrated using a commercial Q22Y MRF machine and a zirconia-based magnetorheological (MR) fluid. The surface of a 38mm diameter by 7.6mm thick puck was processed in a sequence of two figure correction runs. The initial p-v wave front error of 4.5μm was reduced to 0.35 μm, and the average rms surface micro-roughness was reduced from 3.8nm to 0.47nm. The diamond turning marks were eliminated.
