Abstract

In micro EDM, the machinability can be improved by vibrating the electrode, but the optimal vibration mode is not clear. In this study, in order to find the optimal vibration method for improving machinability, we developed a PZT-driven 3-axis vibration system to assist micro EDM. Compared to traditional Z-direction vibration, the 3-axis vibration had higher removability of debris especially when machining high-aspect holes, leading to an increase in material removal rate by a factor of 2. Among various 3-axis vibration modes, the spiral trajectory vibration mode was found to be the most effective, which significantly reduced the electrode wear and machined surface roughness.
