1. What is the Atmospheric Pressure at Electrode Tip Formula?

The atmospheric pressure at electrode tip formula calculates the atmospheric pressure in EDM (Electrical Discharge Machining) processes based on pressure measurements and geometric parameters of the electrode and flushing system.

2. How Does the Calculator Work?

The calculator uses the atmospheric pressure formula:

\[ P_{atm} = \frac{P_r \cdot \ln\left(\frac{R_0}{R_1}\right) - P_1 \cdot \ln\left(\frac{R_0}{r}\right)}{\ln\left(\frac{r}{R_1}\right)} \]

Where:

\( P_{atm} \) — Atmospheric pressure (Pascal)
\( P_r \) — Pressure in the flushing gap (Pascal)
\( R_0 \) — Radius of the electrodes (Meter)
\( R_1 \) — Radius of flushing hole (Meter)
\( P_1 \) — Pressure in flushing hole (Pascal)
\( r \) — Radial location of pressure (Meter)
\( \ln \) — Natural logarithm function

Explanation: This formula calculates atmospheric pressure based on pressure distribution in the EDM flushing system and electrode geometry.

3. Importance of Atmospheric Pressure Calculation

Details: Accurate atmospheric pressure calculation is crucial for optimizing EDM processes, ensuring proper flushing, and maintaining stable machining conditions.

4. Using the Calculator

Tips: Enter all pressure values in Pascal and all radius values in meters. Ensure all values are positive and the radial location is appropriate for the electrode geometry.
