以DEFORM-3 D软件为平台，建立了特定切削三要素下TC4钛合金的三维车削有限元模型，探讨并比较了TC4钛合金在TiN、TiCN和Al2 O3三种涂层刀具切削时切削力和刀具切削温度的变化规律，确定Al2 O3为TC4钛合金最适宜的刀具涂层材料，并对其进行车削用量参数优化，为实际工艺参数的选择提供了理论指导。

Based on the DEFORM-3D software,the 3D turning finite element model of Titanium alloy TC4 under the specified three cutting elements was established. Changing rules of cutting force and tool tempera-ture when TC4 was cutted by the coated cutting tools of TiN、TiC and Al2 O3 was explored, and confirmed that the optimal coated cutting tool material was Al2 O3 . At last, the three cutting parameters was optimized for it. The results provided guiding significance for the determination of process parameters.
