| 摘 要： | 针对目前航空、航天等领域中日益广泛应用的硬质合金等材料出现的切削加工困难、电加工蚀除速度慢的问题，设计了带有放电爆炸力的电火花加工脉冲电源。建立了电火花放电加工的热力学传导模型，通过有限元仿真方法得出具有放电爆炸力的单次脉冲能够明显提高难加工材料蚀除量的结论。加工对比实验证明具有放电爆炸力的脉冲电源能够实现高效、稳定的放电加工。

| Abstract: | Based on the low removal rate of the material like cemented carbide in the space lield by cutting and EDM, a pulse generator discharged with explosion is designed. The heat transfer model of the discharge has been established, and the removal rate could be significant promoted because of the explosion with the method of thermodynamic finite element analysis. Finally the experiments results demonstrated that the generator is capable of high efficiency, high speed, stable machining. |
