摘　　要：为提高钛合金深孔环形套料钻削时的排屑性能,选取TC4钛合金棒材为研究对象,基于响应面法(box-behnken design, BBD)结合仿真试验开展了深孔环形套料钻削切削液参数优化研究。以切削液密度、切削液黏度、切削液流量为三参数输入条件,以第一刀齿断屑槽压力和断屑槽湍流动能为优化目标,建立影响因素与响应值之间的回归模型,探究三参数对响应值的影响规律。试验结果表明,切削液黏度与流量交互对两响应值的影响最大。切削液的最优参数为密度1 100 kg/m^(3)、黏度0.002 kg/(m·s)、流量180 L/min。物理试验验证表明,优化后的切削液可以明显的改善切屑形态,有利于提高排屑性能。To improve chip removal performance during drilling of titanium alloy deep hole annular trepanning.TC4 titanium alloy bar was selected as the research object,and the optimization of cutting fluid parameters for deep hole annular trepanning drilling was carried out based on box-behnken design(BBD)response surface methodology combined with simulation tests.The three parameters of input condition are cutting fluid density,cutting fluid viscosity and cutting fluid flow rate,and the optimization objectives are chipbreaker pressure and chipbreaker turbulence kinetic energy of the first cutter tooth,so as to establish a regression model between the influencing factors and the response values.Explore the law of influence of the three parameters on the response values.The experimental results show that the interaction of cutting fluid viscosity and flow rate has the greatest influence on the two response values.The optimal parameters of cutting fluid are density 1100 kg/m^(3),viscosity 0.002 kg/(m·s),flow rate 180 L/min.Physical test validation shows that the optimized cutting fluid can obviously improve the chip morphology,which is conducive to improving the chip removal performance.
