Ultrasonic Vibration-Assisted Cutting of Titanium Alloy

Although titanium is a very useful material and becoming more in demand, we are faced with difficulties in machining the material. By applying ultrasonic vibration to the tool tip, interrupted cutting can be applied. Using ultrasonic vibration-assisted cutting of titanium alloy, we succeeded in reducing the cutting force. This technology enables us to improve tool wear and surface roughness of the workpiece. In regards to cutting fluid supply methods, it was found that semi-dry cutting was the most suitable for ultrasonic vibration-assisted cutting of titanium alloy.
