钛合金TC4在加工过程中会出现工件变形及黏结等问题，因此加工难度较大。利用ABAQUS软件创建仿真模型，对比了超声椭圆振动车削和常规切削对钛合金TC4力学特点的影响，并对比分析了超声椭圆振动车削钛合金TC4的切削速度、切向幅值、频率和切削深度对切削力的影响。结果表明，超声椭圆振动切削平均切削力随着切削深度及切削速度的增加而增加；随着切向幅值及振动频率的增加而减小；与常规切削相比，超声椭圆振动切削能够明显降低切削力，改善表面加工质量，提高加工效率。

Titanium alloy TC4 will have problems such as workpiece deformation and bonding during the machining process, so the processing is difficult. This study used ABAQUS software to create a simulation model. In this paper, the influence of ultrasonic elliptical vibration turning and conventional cutting on the mechanical characteristics of titanium alloy TC4 was compared, and the influence of the cutting speed, tangential amplitude, frequency and cutting depth of ultrasonic elliptical vibration turning TC4 titanium alloy on the cutting force was analyzed. The results show that the average cutting force of ultrasonic elliptical vibration cutting increases with the increase of cutting depth and cutting speed, and decreases with the increase of tangential amplitude and vibration frequency. Compared with conventional cutting, ultrasonic elliptical vibration cutting can significantly reduce cutting force, improve surface machining quality and improve machining efficiency..
