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.
