摘要
由于高速切削钛合金TC4在高应变率响应的作用下,改善了其切削加工性能,从而提高了钛合金零件的加工质量。但是高速切削TC4时切削区温度很高,可达到800℃以上,刀具容易失效,严重影响工件的加工精度和表面加工质量、刀具使用寿命。利用Deform-3D仿真并分析了切削用量对切削温度的影响及切削区刀具、工件温度场分布规律。仿真与理论分析结果与有关的实验结论具有一致性,证明该仿真软件的可靠性。该研究结论对刀具设计、切削参数的合理选择有重要意义。
Due to the high speed cutting of titanium alloy TC4 in under the action of high strain rate response,it improves the machining performance,so as to improve the machining quality of titanium alloy parts. But the temperature of cutting zone is very high,when high-speed cutting TC4 may achieve above 800℃,the tool is easy to failure,seriously affects the machining accuracy and surface quality of workpiece,and cutting tool life. Uses Deform-3D simulation and analyzes the influence of cutting parameter of cutting temperature and cutting tool,and workpiece temperature field distribution. Simulation and theoretical analysis results and the related experimental results are consistent,proving the reliability of the simulation software. The research conclusion of tool design,and the reasonable choice of cutting parameters is important.
