摘　　要：针对电火花块电极磨削效率高和线电极磨削精度高的优点,采用块电极磨削为微细电极的粗磨削、线电极磨削为微细电极的中、精磨削方式,对大长径比微细电极的制作技术进行研究。通过分析微细电火花加工大长径比微细电极的影响因素,对影响大长径比微细电极制作的加工参数进行了大量的工艺试验,得到各参数对微细电极制作的影响规律,优选得到相关的大长径比微细电极的加工参数,并进行了实验验证。Because of high efficiency of BEDG and high precision of WEDG in processing, combing BEDG and WEDG together to be the method of fabricating micro electrode with large aspect ratio, which contains three steps, the rough processing by BEDG, the intermediate and finish processing by WEDG. Then a group of parameters for the three processing steps are obtained through enormous experiments and made experimen- tal verification.
