摘　　要：针对管电极射流电解铣削加工微槽进行了工艺参数试验研究,结果表明:当其他加工参数不变时,单次加工的微槽尺寸与电流密度成正相关,与进给速度成负相关,多次重复加工微槽可有效增大槽深,但槽宽几乎不变。在此基础上,建立了槽宽和槽深关于电流密度与进给速度的经验公式,以及槽深关于重复加工次数的经验公式,并通过实验验证了经验公式的可行性。The process parameters of tube electrode jet electrochemical milling micro-groove were studied. The result showed that when other processing parameters remain unchanged,the size of the micro-groove in a single time is positively correlated with the current density and negatively correlated with the feed speed. Meanwhile,repeated processing of the micro-groove can effectively increase the groove depth,but the groove width is almost unchanged. Based on the above result,the empirical formulas of groove width and depth on current density and feed speed,and groove depth on repeated machining times were established. Finally,the feasibility of the empirical formula was verified by experiments.
