Abstract
As a hard-to-machine material, titanium alloy has a combination of superior heat resistance, corrosion resistance, and mechanical properties, and this leads to poor machinability. High cutting forces and cutting temperature greatly accelerate tool wear during the cutting of titanium alloy frequently. In this article, the ultrasonic vibration turning method was adopted to reduce the wear of diamond tool in the turning of TC4 titanium alloy. Ultrasonic vibration turning tests were carried out in a variety of cutting parameters. The experimental results indicated that the wear of diamond tool was significantly reduced during the turning of TC4 using the ultrasonic vibration turning. In the ultrasonic vibration machining tests, the tool vibration amplitude and frequency are the primary and most influential factors on tool wear, followed by the feed rate and then the cutting depth.
