钛合金具有良好的耐腐蚀性和耐热性，广泛应用于航空航天、医疗设备等高精度领域。在传统的微细电火花加工中，当加工孔径较小、长径比较大时，难加工材料的小深孔加工一直是个难题，存在排屑困难、加工效率低等问题。针对上述缺点，将高频超声振动引入微细电火花加工中，以改善加工性能。并通过解析计算、有限元仿真、阻抗测试、误差分析等方法对优化后的超声系统进行设计。将该系统应用于SE-WK008型微孔机上，进行了超声参数与电参数(加工电压、脉冲宽度、脉冲间隔、峰值电流)的单变量控制实验。总结了各参数对加工效率和电极损耗的影响规律，并用多项式曲线对实验数据进行了拟合，然后利用多目标粒子群算法(MOPSO)找出最优参数组，验证了所选加工参数组的正确性。通过实验分析，所设计的超声系统可以应用于传统的微孔机，最高加工效率提高82.7%，最大电极损耗降低68.7%，为实际小深孔加工的参数选择指明了方向。
Titanium alloy is widely used in high-precision fields such as aerospace industries and medical equipment because of its corrosion resistance and heat resistance. In conventional micro-EDM, the machining of small deep holes of difficult-to-cut materials has always been a problem due to difficult waste debris discharge and low machining efficiency when the machined aperture is small and the aspect ratio is large. Based on the above shortcomings, the high-frequency ultrasonic vibration was introduced into micro-EDM to improve processability. And the optimal ultrasonic system was designed on analytical calculation, finite element simulation, impedance test, and error analysis. The system was applied to SE-WK008 microporous machine for titanium alloy drilling test, and the univariate control experiment based on ultrasonic parameters and electrical parameters (processing voltage, pulse width, pulse interval, and peak current) was carried out. The influence law of each parameter on processing efficiency and electrode wear was summarized and the experimental data was fitted with polynomial curves, and then the multi-objective particle swarm optimization (MOPSO) algorithm was used to find out the optimal parameter array to verify the correctness of the selected processing parameter group. Through experimental analysis, the designed ultrasonic system can be applied to the traditional microporous machine, the highest processing efficiency is increased by 82.7%, and the maximum electrode wear is reduced by 68.7%, which points out the direction for the parameter selection of actual small deep hole machining.
