摘　　要：以钛合金Ti6Al4V作为研究对象,使用有限元分析软件ABAQUS进行二维切削仿真,研究切削过程中刀具前角、切削速度以及切削深度对切削力以及切削温度的影响。采用正交试验法对仿真结果进行极差分析研究各因素对各指标的影响程度,再运用排名评分法寻找在切削力以及切削温度最小下的最优工艺参数组合。仿真实验以及极差分析结果表明:刀具前角是垂直切削运动方向切削分力RF2的主要因素,切削深度是切削运动方向上的切削力RF1以及切削过程中最高温度Max.Temp的主要因素。最终得出的最佳工艺参数为刀具前角10˚,切削速度1m/s,切削深度0.5mm。In this paper,titanium alloy Ti6Al4V is used as the object of study,and the finite element analysis software ABAQUS is used to simulate two-dimensional cutting to study the effect of tool front angle,cutting speed and depth of cut on cutting force and cutting temperature during the cutting process.The orthogonal test method is used and the simulation results are analyzed by range analysis to study the influence of each factor on each index,and then the ranking score method is used to find the optimal combination of process parameters with minimum cutting force and cutting temperature.The simulation experiments and the results of the range analysis show that the tool front angle is the main factor of the cutting part force RF2 in the direction of vertical cutting motion,and the depth of cut is the main factor of the cutting force RF1 in the direction of cutting motion and the maximum temperature during cutting.The final best process parameters are derived as tool front angle 10˚,cutting speed 1 m/s and depth of cut 0.5 mm.
