A Study of Micro Machining with Instantaneous Tiny-Grinding Wheel Based on the Fe<,3>O<,4> Magnetorheological Fluid
In this study, Fe<,3>O<,4> particles were used as magnetic particles to form Fe<,3>O<,4> magnetorheological (MR) fluid, and experiments were conducted to polish optical glass using this Fe<,3>O <,4> MR fluid. The machining characteristics of glass surface with different MR fluids that are added diamond abrasives and short fibres are studied. Experimental results indicate that the tiny-grinding wheel based on the Fe<,3>O<,4> MR fluid can effectively polish optical glass and that the maximum diameter and depth of machined region increase obviously in the presence of diamond abrasives and short fibres. When both of diamond particles and short fibres are added to the Fe<,3>O<,4> MR fluid, the removal efficiency of the tiny-grinding wheel is markedly enhanced due to the synergetic effect of diamond abrasives and fibres.
