  • Abstract Abstract
      Most of the research used the rectified DC voltage to machine the micro-hole on the Borosilicate Glass in ECDM process. One of the  drawbacks is seriously inlet reaming. Extremely, the material will form micro-crack because of continuously discharge spark. This study investigate the shape accuracy and size of the micro-hole and the machining time with changing the electrode geometry, finding the best switch on and switch off time ratio, and adding surfactant into the dielectric.
    The experimental results show that the reaming of the micro-hole decrease 20% by changing cylinder electrode into flat side wall electrode, 28% by adding the best surfactant concentration combined the flat side wall electrode.
    Finally, the flat side wall electrode combine the pulse voltage and add surfactant into dielectric. The result shows the distinct improvement in the inlet reaming and the machine time
