摘要：

An experimental analysis of orthogonal cutting of a Ti-6Al-4V alloy is proposed. Cutting speeds are explored in a range from 0.01 to 73 m/s by, using an universal high-speed testing machine and a ballistic set-up. The evolution of the cutting force in terms of the cutting speed and the development of adiabatic shear banding are analyzed. The shear band width and the distance between bands have been determined by micrographic observations. Their dependence upon the cutting velocity is analyzed. A modeling is proposed which restitutes well this velocity dependence. (C) 2002 Elsevier Science Ltd. All rights reserved.
