文摘

Micro-electrodes are used for micro EDM of miniaturized products. Developing new fabrication and measurement techniques of micro-electrode are simple and cheap. Micro-electrode can be fabricated and measured in workshop by usual EDM machine. The highest aspect ratio (more than 60.25) of micro-electrode was fabricated. It had 78.19 μm diameter and 4.70 mm length after producing hole on WC (134.5 μm).
