对Ti-6Al-4V合金进行了正交切削试验分析。切削速度范围从0.01到73米/秒的探索，使用通用高速试验机和弹道设置。分析了切削力随切削速度的变化规律和绝热剪切带的发展规律。通过显微观察确定了剪切带宽度和剪切带间距。分析了它们对切削速度的依赖关系。提出了一个模型，恢复以及这种速度的依赖性。(C)2002爱思唯尔科技有限公司版权所有。
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.
