摘　　要：针对钛合金在NaNO3电解液下易钝化而导致电解加工中断的问题,提出了钛合金微铣削辅助电解复合加工方法,首先设计了微铣削辅助电解复合加工工具,建立了复合加工深度轮廓的数学模型,并通过单因素试验研究了不同进给速度、主轴转速、加工电压对复合加工的影响。结果表明:这些参数中对复合加工深度和材料去除率影响最大的是进给速度,对轮廓定域性影响最大的是主轴转速。在进给速度3 mm/min、加工电压24 V、主轴转速2000 r/min的试验参数下,加工获得的表面质量效果较好,加工深度轮廓试验曲线与数学模型达到了较好的吻合。A titanium alloy micromilling assisted electrochemical composite machining method was proposed to address the issue of titanium alloys easy to passivate in NaNO3 electrolyte,leading to interruptions in electrochemical machining.Firstly,a micromilling assisted electrochemical composite machining tool was designed,and a mathematical model for the depth profile of composite machining was established.Then,the effects of feed rate,spindle speed and machining voltage on composite machining were studied through single factor experiment.The result indicated that among these parameters,the feed rate has the greatest impact on the depth of composite machining and material removal rate,while the spindle speed has the greatest impact on the localization of the contour.Under the parameter of feed rate of 3 mm/min,processing voltage of 24 V and spindle speed of 2000 r/min,the surface quality obtained is better and the experimental curve of machining depth profile is in great agreement with the mathematical model.
