摘要

摘要: 为了减轻钛合金干式切削时的刀具磨损，提高试件表面质量，提出了一种水基切削液超声雾化辅助切削的方法。首先，以TC4钛合金为切削对象，进行了钛合金干式切削试验。然后，以纳米级水溶性油基切削液与去离子水混合后形成的乳化液为雾化介质，由超声雾化器转化为微小液滴并作用于刀工界面，进行了超声雾化辅助切削试验。最后，对比分析了超声雾化辅助前后，TC4工件表面粗糙度、刀具磨损、元素扩散和切屑形貌等情况。实验结果表明：与干式切削相比，超声雾化辅助切削后的钛合金表面粗糙度降低47.6%、后刀面刀具磨损值最大降低36 μm、刀具表面Ti、O元素含量分别从78.72%、6.32%减少到75.49%、1.85%。

Abstract: In order to reduce the tool wear and improve the surface quality of titanium alloy, an ultrasonic atomization assisted cutting method with water-based cutting fluid was developed. Firstly, TC4 titanium alloy was used as the cutting material, and the dry cutting experiment of TC4 titanium alloy was carried out. Then, the emulsions formed by mixing nano water-soluble oil-based cutting fluid and deionized water are used as the atomizing media, which were transformed from ultrasonic atomizer into tiny droplets and act on the tool interface. The ultrasonic atomization assisted cutting experiment was carried out. Finally, the surface roughness, tool wear, element diffusion and chip morphology of TC4 workpiece before and after ultrasonic atomization were compared. The experimental results show that the surface roughness of TC4 titanium alloy increased by 47.6%, the wear value of cutting tool on the back face reduced by 36 μm, and the Ti and O contents on the surface of cutting tool reduced from 78.72%, 6.32% to 75.49% and 1.85% , respectively.
