NANO-FABRICATION & ELECTROCHEMICAL CAM

USP Electrochemical Micromachining (EMM) Calculator

Calculate double-layer charging time ($ au_c$), sub-nanosecond pulse dissolution localization radius ($r_{ ext{loc}}$), frontal equilibrium gap ($y_0$), and micro-electrode overcut offsets.

1. Pulse & Electrolyte Parameters

Voltage Pulse Width ($t_p$ in ns)

Ultra-short pulse duration (sub-microsecond regime).

Electrolyte Conductivity (κ in S/m)

e.g., 1M NaNO3 or H2SO4 solution.

Nominal Frontal Gap ($d_0$ in µm)

Standoff between tool cathode and anode workpiece.

Pulse Voltage ($U$ in Volts)

Peak pulse voltage amplitude.

Cathode Feed Rate ($v_{ ext{feed}}$ in µm/s)

Linear micro-tool advance velocity.
