作者研制了一种高频响应的作动器，它被用作传统电火花加工机床的适配器。利用该适配器，研究了频率响应对加工稳定性和加工速度的影响。实验结果表明：（1）精加工条件下的流体冲洗加工（10μmRmax）;（2）高光加工条件下的跳跃加工（1μmRmax）;（3）微小孔（≤ 240μm）的加工速度提高约1.5-2.5倍。然而，在精加工条件下具有跳跃动作的加工的加工速度（10μmRmax）没有提高。加工速度提高的差异定性地解释了加工间隙中磨屑行为的差异。
The authors developed a high frequency response actuator which is used as an adaptor for a conventional electric discharge machine. With the adaptor, the effects of frequency response to machining stability and machining speed were examined. Experimental results show that machining speed was improved by roughly 1.5-2.5 for (1) the machining with fluid flushing on the finishing condition (10μmRmax) (2) the machining with jump action on the high-gloss finishing condition (1μmRmax) (3) the machining of the micro-hole (∅240μm). The machining speed for the machining with jump action on the finishing condition (10μmRmax), however, was not improved. The difference of the improvement in the machining speed is explained qualitatively by the difference of the behavior of debris in the machining gap.
