| 摘 要： | 对磁流变抛光液在抛光区域的固态核分布进行了理论分析。在这基础上,以Preston方程为根据,即被加工工件表面材料去除率与压力参数p成正比的关系,该压力由磁化压力和流体动压力组成,建立磁流变抛光的材料去除数学模型。在自研的试验装置上利用磁流变抛光方法加工BK7平面镜工件,验证了数学模型的合理性。

| Abstract: | Magnetorheological finishing (MRF) is a newly developed method for finishing optical component. The Tin-sheared region in the flow between wheel and part which called cores is described. The distribution of the cores is analyzed. According to Preston equation, material removal model of magnetorheological finishing (MRF) is established. The pressure acting on the surface of the part is analyzed. Piece of flat surface glass is polished on the MRF experimental facility which is developed by ourselves. The reliability of the model is verified by the experiment. |
