摘　　要：应用ABAQUS/Explicit软件建立了钛合金Ti6Al4V的二维正交切削模型,采用温度—位移耦合分析步,研究了CBN刀具二维正交切削Ti6Al4V时切削参数及刀具前角对切削温度的影响。研究结果表明,切削速度、切削厚度的增大均会使切削温度升高,其中切削速度对切削温度的影响最大,切削厚度次之;切削温度随着刀具前角的增大而降低,但当前角继续增大至20°后,切削温度略有上升。切削区高温分布区域随切削速度的增加而有所减小,随着切削厚度的增加,切削区高温分布区域增加。It uses ABAQUS/Explicit software to establish a two-dimensional orthogonal cutting model of titanium alloy Ti6Al4V, with the coupled temperature-displacement analysis of step, researching the effect of cutting parameters and tool rake angle on cutting temperature of CBN tool two-dimensional orthogonal cutting Ti6Al4V. The researching result shows that cutting temperature rises with cutting speed and thickness increased. And the influence of the cutting speed is the max- imum, cutting thickness is smaller. The cutting temperature decreases with the increase of the rake angle, but when the rank angle increases to 20° , cutting temperature rise slightly. High temperature distribution of cutting area decrease with the increase in cutting speed, and incease with the cutting thickness increased.
