N2 - In recent years, there has been a growing demand for micro holes. However, electrochemical machining has rarely been employed in drilling these holes because of problems with electrolyte diffusion. In this research, a semi-cylindrical tool was used as a tool electrode to increase the flow space of the electrolyte, and electrolyte diffusion was improved via the application of ultrasonic vibrations. Micro holes with a specified diameter of 76 μm were drilled on a 304 stainless steel plate of 300μm thickness. The proposed technique reduced both the machining time and the machining gap.
