为了改善C/SiC复合材料铣削表面质量，研究了超声扭转振动铣削对表面粗糙度的影响。通过对C/SiC复合材料进行超声扭转振动及传统铣槽加工试验，结合Box-Behnken响应曲面试验分析，得到了超声扭转振动铣削条件下各切削要素(主轴转速、进给速度、切削深度)对表面粗糙度的显著性，并建立了表面粗糙度预测模型。研究表明：与传统铣削相比超声扭转振动铣削可有效降低铣削表面粗糙度；各加工要素对表面粗糙度影响重要程度依次为切削深度，主轴转速，进给速度；在试验工艺范围内表面粗糙度预测模型准确可为切削参数优选和表面粗糙度控制提供依据。

In order to improve surface quality of milled surfaces of carbon fiber reinforced silicon carbide ( C/SiC) composites,the influence ofultrasonic torsional vibration milling on surface roughnesswas investiga-ted. Based on the tests of ultrasonic torsional vibrationand traditional slotmilling, combined with Box-Be-hnken response surface test analysis,the significance of each factor of processing parameters ( spindle speed, feed rate, depth of cut) on surface roughness was studied,and the prediction model of surface roughness was established. The experimental results show that ultrasonic torsional vibration milling can effectively reduce the surface roughness compare with conventional milling;depth of cut is the most significant factor of affect-ing surface roughness in UTVM with spindle speed, feed rate being the second, the third;surface roughness prediction model can accurately provide the basis for the surface roughness and cutting parameters optimiza-tion control within the range of experiment process.
