Abstract
Titanium alloys exhibit superior properties such as high strength-to-weight ratio and
corrosion resistance but these alloys possess poor machinability. To overcome this
disadvantage, new machining methods (Ultrasonic Assisted Machining, Hot Machining
etc.) are developed. Hot Ultrasonic Assisted Turning (HUAT) is a new machining method
which changes the cutting system between tool and workpiece therefore reduced cutting
forces and better surface finish for workpiece are obtained. In this study, 2D finite
element (FE) analysis was carried out to investigate the effects of HUAT for titanium
alloys. It was confirmed that HUAT technique reduces cutting forces and effective stress
significantly but cutting temperature increases compared to conventional turning.
