在本文中，我们提出了一种利用串联电火花加工（EDM）机构同时加工多边形微电极和微孔的方法。在同一台机器上安装了两种电源，分别用于多角形柱电极的成形和孔加工。使用具有目标形状的掩模板来形成电极。对掩膜板进行平面运动，通过缩径操作得到多边形微柱电极。在此过程中，选择了掩膜板的低磨损条件和电极的高磨损条件。电极材料采用易电火花加工成型的锌合金。电极形成后，使用该电极在钨板上钻出多边形微孔。用锌合金电极加工微孔的去除率高于相同形状的铜电极。为了实现微电极和微孔的同时加工，构建了串联结构机构。在适当的条件下，采用串列电火花加工机构实现了多角形微孔的连续加工。
In this paper, we propose the simultaneous machining of a polygonal microelectrode and microholes using a tandem electrical discharge machining (EDM) mechanism. Two types of power sources for forming the polygonal pillar electrode and hole machining were installed on the same machine. A mask plate with the target shape is used to form the electrode. Planar motion was applied to the mask plate, and a polygonal micropillar electrode was produced by reducing operation. In this process, the low wear condition of the mask plate and the high wear condition of the electrode were chosen. Zinc alloy, which is easy to form by EDM, was used for the electrode material. After the electrode was formed, polygonal microholes were drilled into a tungsten plate using this electrode. Microhole machining with a zinc alloy electrode resulted in a removal rate that was higher than that with a copper electrode of the same shape. To perform simultaneous machining of a microelectrode and microholes, a tandem structure mechanism was constructed. Continuous polygonal microhole machining was attained by applying the tandem EDM mechanism under the appropriate conditions.
