摘　　要：为获得抛光均匀的铝合金阳极氧化膜表面,采用集群磁流变平面抛光技术对铝合金阳极氧化膜进行抛光试验,探讨加工间隙、工件转速、抛光盘转速、偏摆幅度、加工时间等加工参数对其表面粗糙度和材料去除率的影响规律。结果表明:随着加工间隙的增大,工件表面粗糙度先减小后增大,材料去除率则递减;随着工件转速或偏摆幅度的增加,工件的表面粗糙度均先迅速减小后缓慢增大,材料去除率则先增加后减小;随着抛光盘转速的增加,工件的表面粗糙度和材料去除率均先减小后增加;随着加工时间的延长,表面粗糙度迅速减小之后趋于稳定。在文中试验条件下,在加工间隙1. 1 mm、工件转速350 r/min、抛光盘转速60 r/min、偏摆幅度10 mm、加工10 min左右时工件表面粗糙度从原始的332. 9 nm下降至5. 2 nm,达到了镜面效果。In order to obtain the uniform polishing surface,the polishing experiments of anodic oxide film of aluminum alloy were conducted by the cluster magnetorheological finishing(MRF)technology to research the influence of main polishing parameters on the surface roughness and material removal rate,including the machining gap,the revolving speed of the workpieces and the polishing plate,the oscillation distance of the workpiece,and the machining time.The results show that with the increasing of the machining gap,the surface roughness of the workpiece is decreased firstly and then increased,while the material removal rate is decreased rapidly.With the increasing of the revolving speed or the oscillation distance of the workpieces,the surface roughness is first decreased rapidly and then increased slowly,while the material removal rate is increased at first and then decreased.Both the surface roughness and material removal rate are decreased at first and then increased with the increasing of the revolving speed of the polishing plate.With the extension of the machining time,the surface roughness of anodic oxide aluminum alloy is decreased rapidly and then tends to be stable.The surface roughness of the polished workpieces is decreased from 332.9 nm to 5.2 nm and a mirror surface of anodic oxide film of aluminum alloy is obtained with the machining gap of 1.1 mm,the revolving speed of the workpieces of 350 r/min,the revolving speed of the polishing plate of 60 r/min,the oscillation distance of 10mm and the machining time of 10 min under the experiment conditions in this paper.
