Abstract: In the titanium alloy cutting operations with carbide tools, tool wear is one of the main restrictive factors on its tool life, and the cutting temperature significantly affects the tool wear, and closely related to work piece surface integrity and machining precision. Therefore, the analysis of temperature changes of cutting temperature and the tool wear are helpful to increase the productivity and lower down the costs of production. In this paper, the finite element software Deform3D was used to make simulation analysis on cutting temperature field and tool wear during the process of titanium alloy cutting operations with carbide tools. Accoordingly, the influence of the cutting speed, feed and cutting depth, and the dynamic changes of the rake angle of the tool on cutting temperature was achieved, and the change law of tool wear condition with cutting temperature. The findings of this research are helpful to optimize the cutting parameters and research the mechanism of tool wear.
