摘　　要：根据超声振动研磨加工原理,采用自行研制的超声振动研磨装置对塑性难加工材料钛合金(TC4)表面粗糙度特性进行了试验研究。试验采用单因素法,分别研究了工件转速、超声振动振幅以及磨料粒度对工件表面粗糙度的影响规律。试验结果表明:超声振动的附加在一定程度上降低了工件表面粗糙度。所获得的结论对超声振动研磨中加工参数的选择具有一定的参考价值。Based on the machining principle of ultrasonic vibration lapping, the surface roughness characteristics of hard-to-machine titanium alloys were studied through experiments using self-developed ultrasonic vibration lapping device. The influence law of workpiece speed, ultrasonic amplitude and abrasive grain size on the machined surface roughness were researched by using single-factor testing method. The research results show that surface roughness is reduced to some extent owing to the assistance of ultrasonic vibration. The conclusions provide a certain reference for the optimization of processing parameter in ultrasonic vibration lapping.
