电化学放电加工 (ECDM) 是一项很有前途的玻璃和其他非导电材料 3D 微结构技术。 ECDM 是一种桌面技术，不需要洁净室且空间占用适中，因此使 ECDM 适合微型工厂。如今，重力进给钻孔是 ECDM 微孔钻孔最常用的方法。然而，实验表明，重力进给设置可能会导致许多问题，从而降低加工的重复性。本文提出了一种实现有效微钻孔的新方法，称为反阻力微孔钻孔。此外，还研究了作用在加工过程中的变化力。实验表明，与传统的重力进给方法相比，可重复加工得到了显着改善。同时，对这种新钻井方法进行了系统分析。实验表明，力是影响钻井过程的关键因素之一，特别是在水动力状态下。
Electrochemical discharge machining (ECDM) is a promising technology for 3D microstructuring of glass and other non-conductive materials. ECDM is a table-top technology that requires no clean room and has a modest space usage and therefore making ECDM suitable for microfactories. Nowadays, gravity-feed drilling is the most commonly used method for micro hole drilling with ECDM. However, experiments show that gravity-feed set-up may lead to many issues that lower the repeatability of machining. In this paper, a new method is proposed to achieve effective micro-drilling, under the name of counter resistant micro-hole drilling. Furthermore, the varied force acting on machining process was investigated. The experiments demonstrated that reproducible machining was significantly improved over the conventional gravity-feed method. Meanwhile, a systematic analysis of this new drilling method was characterized. The experiments showed that the force is one of the key factors that influence the drilling process, especially in the hydrodynamic regime.
