ABSTRACT Nowadays, finite element analysis is the best suitable approach to reduce the need for several experiments. This paper is based on the FE modeling and model validation via the experimental value of turning operation in 2D on heat-treated Titanium alloy (Ti-10-2-3 is also named as Ti-10 V-2Fe-3Al). Turning operation is treated as an orthogonal cutting process and this operation is simulated using Abaqus® explicit 6.14 software, with the help of Johnson–Cook material constructive model with boundary conditions. FE simulation results were validated with experimentally obtained forces and cutting temperatures during turning operation on different cutting thickness. Simulation and the experiment were conducted on the three different heat-treated conditions of the Ti-10-2-3 like Solution Treatment and Aging (STA), Annealed and Solution Treated and Overaged (STOA). The model validation showed that the average errors in the prediction and the experimental values are cutting force 4%, feed force 3% and temperature 11%. In this model, the simulated value of the average feed force was slightly less than the experimental value due to the consideration of actual friction between tool–chip interfaces on the rake face.

热处理 Ti-10-2-3 的正交加工：有限元和实验

摘要 如今，有限元分析是减少多次实验需求的最佳方法。本文基于有限元建模和模型验证，通过在热处理钛合金（Ti-10-2-3 也称为 Ti-10 V-2Fe-3Al）上进行二维车削操作的实验值。车削操作被视为正交切削过程，该操作使用 Abaqus®显式 6.14 软件在具有边界条件的 Johnson-Cook 材料构造模型的帮助下进行模拟。有限元模拟结果通过实验获得的力和不同切削厚度的车削操作过程中的切削温度进行验证。模拟和实验在 Ti-10-2-3 的三种不同热处理条件下进行，如固溶处理和时效 (STA)，退火和固溶处理和过度老化 (STOA)。模型验证表明，预测和实验值的平均误差为切削力 4%、进给力 3% 和温度 11%。在该模型中，由于考虑了前刀面上刀具-切屑界面之间的实际摩擦，平均进给力的模拟值略小于实验值。
