1. What is the Supply Voltage Calculation?

The Supply Voltage calculation determines the voltage required for electrochemical machining processes based on the gap between tool and work surface, electrolyte properties, workpiece characteristics, and process parameters.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_s = \frac{h \times r_e \times \rho \times V_f}{\eta_e \times e} \]

Where:

\( V_s \) — Supply Voltage (V)
\( h \) — Gap between tool and work surface (m)
\( r_e \) — Specific resistance of the electrolyte (Ω·m)
\( \rho \) — Work piece density (kg/m³)
\( V_f \) — Feed speed (m/s)
\( \eta_e \) — Current efficiency in decimal
\( e \) — Electrochemical equivalent (kg/C)

Explanation: This formula calculates the required supply voltage for electrochemical machining based on various process parameters and material properties.

3. Importance of Supply Voltage Calculation

Details: Accurate supply voltage calculation is crucial for optimizing electrochemical machining processes, ensuring proper material removal rates, and maintaining process stability and efficiency.
