This work focuses on the 3D numerical investigation of machinability criteria using textured tools for the dry machining of titanium grade 2. For the development of the 3D finite element model, DEFORM-3D (version 10.1) software was used. Dimple patterns were created nearer to the cutting edge region on the rake face of carbide inserts so as to predict their effect and investigate the machinability criteria. Comparison of dimple-textured tool was being made with a conventional tool based on the cutting forces (Fx, Fy and Fz), cutting temperature, tool wear, effective stress and effective strain. The numerical study revealed that the dimple-patterned tool improved the machinability of titanium grade 2. The cutting forces (tangential cutting force, feed force and radial force) reduced while machining with a dimple-patterned tool as compared to the conventional nontextured tool. There was an enhancement of tool life and a decrease in effective stress and effective strain while dry turning grade-2 titanium alloy using the textured tool.

使用纹理工具加工钛等级 2 的 FEM 仿真评估

这项工作的重点是使用纹理工具对钛等级 2 的干加工进行可加工性标准的 3D 数值研究。为了开发 3D 有限元模型，使用了 DEFORM-3D（10.1 版）软件。在靠近硬质合金刀片前刀面上的切削刃区域处创建凹坑图案，以预测它们的影响并研究可加工性标准。基于切削力（FX,F是的和Fz)、切削温度、刀具磨损、有效应力和有效应变。数值研究表明，带凹坑的刀具提高了钛等级 2 的可加工性。与传统的无纹理刀具相比，使用带凹坑的刀具进行加工时，切削力（切向切削力、进给力和径向力）降低了。使用织构刀具干车削 2 级钛合金时，刀具寿命延长，有效应力和有效应变降低。
