摘　　要：钛合金属于难加工材料,干粗车切削温度较高。本文运用Deform—3D建立钛合金Ti6Al4V的三维车削有限元模型,通过正交实验设计方法设计Ti6Al4V车削模拟方案,分析不同的切削用量对切削温度的影响。最后利用MATLAB软件建立了车削钛合金过程中车削速度、进给量、被吃刀量与切削温度的回归方程,得出了钛合金切削过程中切削用量与切削温度之间的变化规律,并构建了干粗车钛合金时的切削温度预测模型,为研究金属切削过程提供了一种新的思路。Titanium alloy belongs to difficult-to-cut materials, the temperature of dry rough cutting is high. The three-dimensional finite element model of turning titanium alloy Ti6Al4V was established by Deform-3D. By using the Ti6Al4V turning simulation scheme based on orthogonal experiment design method, the influence of cutting parameters on cutting temperature was analyzed. Regression equation between cutting speed, feed rate, cutting depth and cutting temperature of the process for turning titanium alloy cutting were established by MATLAB, the change rule between the cutting process of titanium alloy in the amount and cutting temperature were draw, and the prediction model of cutting temperature dry rough turning of titanium alloys was built. It provides a new way for the study of metal cutting process.
