“…Thus, development of new polishing techniques has been a research focus for curved surface. A variety of polishing processes using a special fluid whose viscosity can be adjusted by an external field have been developed, such as magnetorheological finishing (MRF) (Kordonski and Jacobs, 1995;Jha and Jain, 2004), electrorheological fluid-assisted polishing (Suzuki et al, 1997), electrophoretic polishing (Kim et al, 2003), magnetic fluid float polishing (Raghunandan et al, 1997;Shimada et al, 2003), magnetic abrasive polishing (Kim and Choi, 1997). MRF is a flexible machining method by using magnetorheological fluid while magnetic field is applied during the processing.…”

Abstract:A new polishing method shear thickening polishing (STP) was proposed to improve the polishing efficiency in the process to obtain extremely smooth curved surfaces. A non-Newtonian fluid with shear thickening property was utilised as the base fluid of the polishing slurry, in which the abrasives were dispersed. In this study, the influence of polishing speed, abrasive concentration and abrasive size on the surface roughness and material removal rate were investigated by experiments. The experimental results revealed that the polishing speed has the greatest influence on the polishing effect. With the increase of the polishing speed, the material removal rate increases rapidly and smoother surfaces with better roughness can be obtained. Abrasive concentration affects the polishing results in a manner that is similar to polishing speed. Abrasive size seems to have no effect on the surface roughness, but material removal rate increases as the abrasive size decreases. Finally, surface roughness of bearing steel work-piece (Ø35 mm) was reduced rapidly from Ra = 105.95 nm to Ra = 6.99 nm after one hours' processing under the appropriate conditions.

“…At last, average surface roughness of 2.9 nm was obtained as a result of the polishing of silicon surface whose initial average roughness was about 50 nm. There were also efforts to establish better understanding of processes in modelling of the electromechanical features by Kim et al [11], improving of the surface roughness on Tungsten carbide moulding dies by Kaku et al [12], and finding the effective area in ER polishing and Zhang et al [13]. However, in previous works, polishing the non-conductive material such as optical glass, an auxiliary electrode is needed to surround the glass surface to be polished.…”

Electrorheological (ER) finishing utilizes the flow of electrically stiffened abrasive fluid through a preset converging gap formed by the work-piece surface and a moving tool. An ER finishing tool characterized by cathode integrated with anode together is proposed, whose electric field distribution is finite-element-analyzed (FEA) and is useful to finish both conductive work-piece and non-conductive ones. Experiments were performed to finish a K9 glass by this tool. After 30 minutes polishing, the surface roughness was reduced from 8.46 to 2.53 nm Ra which is better than previously reported 2.9 nm. The result verified the validity of the integrated-electrodes tool for non-conductive optical glasses.
