摘　　要： 利用Fe3O4基电流变液对玻璃材料进行抛光加工试验,考察了抛光截面的形状特征,研究了加工间隙、电场强度对玻璃工件的材料去除的影响。结果显示电流变效应微磨头定点抛光的加工痕迹呈近似"U"形,材料去除率取决于磨料与工件表面的研磨压力和相对速度的共同作用,材料去除量随着外加电压的增大而呈线性增大,而随加工间隙的增大而线性减小。 Experiments were conducted to reveal the polishing properties of the Fe3O4-based electrorheological fluid which was used to form a dynamical,instantaneous tiny-grinding wheel to polish optical glass.The profile of the polished area of the glass surface indicates that the material removal process is dominated by the synergy of the applied pressure and the relative velocity between the abrasives and the polishing workpiece.It is also found that the material removal rate is directly proportional to the intensi...
