Enhancement mechanism of electrochemical drilling square-small holes with workpiece vibration KU Leuven
Square-small holes are used as a critical feature in the fields of aerospace, machine-tooling, automation, and mechanical component construction. Electrochemical drilling (EC-drilling) is a promising approach for manufacturing square-small holes. However, the distribution of flow field in the inter-electrode gap (IEG) becomes non-uniform because of the unique structure of the square-cross-section tubular tool, leading to the accumulation of ...
