Abstract
A cutting-extrusion phenomenon is found during high-speed ultrasonic vibration turning Ti-6Al-4V alloys. The flank face interference in the cutting process is regarded as the explanation of this phenomenon. After then, contrast experiments on surface roughness and surface residual stress are conducted, respectively. The results demonstrate that during the high-speed ultrasonic vibration turning process, a surface roughness of no more than Ra 0.4 is realized and the surface residual stress turns to a compressive one compared to conventional turning.
