Micro EDM milling using deionized water as dielectric fluid was investigated. After machining micro grooves using deionized water with different voltage. capacitance. and resistivity of deionized water, machining characteristics were investigated. The wear of a tool electrode and the machining time can be reduced by using deionized water instead of kerosene. Micro hemispheres were machined in deionized water and kerosene and their machining characteristics were compared.

Micro EDM milling using deionized water as dielectric fluid were investigated. By micro EDM milling, micro structures such as micro grooves were machined on stainless steel. After machining micro grooves with different voltage, capacitance, and resistivity of water, machining characteristics such as gap, tool wear, maximum feedrate and surface quality were investigated. The wear of a tool electrode can be reduced by using deionized water. With different dielectric fluids, kerosene and deionized water, micro hemispheres were machined and their machining characteristics were compared.
