| 摘 要： | 介绍一种等面积分流法的小孔电火花加工方法，分析等面积电极放电的电火花加工过程，重点研究在等面积电极条件下，等面积单电极与分流多电极加工对加工速度、电极损耗、放电间隙的影响。进行了验证性试验，研究结果表明：小孔分流法加工与单电极加工相比，使加工速度略有减小、放电间隙略有变小、电极损耗略有增加，加工效果具有一致性；分流法电火花加工有利于小孔电火花加工的尺寸控制，通过等面积分流法改变加工工艺，用电火花机床稳定加工参数进行小于机床稳定加工临界值的更小尺寸的小孔加工，是一种新的微小孔电火花加工方法。

| Abstract: | A new method of Electrical Discharge Machining(EDM) for small-holes was presented, in which the critical value of machining could be less than that generated by a primitive EDM system. The characters of small-hole EDM in an area equalization by the current dividing were studied,and the effects of the current dividing on the drilling speed,electrode wear and the discharge gap were researched. Research results provide a deeper understanding for the small-hole EDM in area equalization by the current dividing. ... |
