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.
