分别采用超声磨削和普通磨削加工方法加工了几种脆性光学材料，研究了几种主要工艺参数对工件加工表面粗糙度的影响。结果表明，超声频率和振幅、金刚石磨料粒度、切深、工具的横向进给速度和旋转速度等工艺参数对表面粗糙度的影响较大。通过比较发现，超声磨削方法比普通磨削方法具有更好的加工表面粗糙度，更高的材料去除率，以及更低的工具磨损量。

Ultrasonic vibration grinding (UVG) and conventional grinding experimental studies were conducted on several brittle optical materials by altering many processing parameters (such as vibration frequency and amplitude,diamond abrasive grit size,cutting depth,transverse speed and rotary speed of tool). The experimental results show that the machined surface roughness for the brittle optical materials are greatly influenced by these processing parameters. By comparison,it is found that the surface roughness is reduced by UVG method. At the same time,the material removal rate increases and the wear extent of tool is reduced greatly.
