Question

What is the value of gap maintained between the electrodes while machining with Electro Discharge Machining?

• A. 10 – 100 µm
• B. 100 – 200 µm
• C. 200 – 500 µm
• D. 500 – 1000 µm

Hint:

Maintaining the correct gap size is crucial in EDM to balance machining accuracy and efficiency. Ensure the gap is between 100 and 200 µm for optimal results.

Answer 1

The Correct Option is B

In Electro Discharge Machining (EDM), the gap between the electrodes is critical for the machining process. Typically, the gap is maintained between 100 – 200 µm. This gap ensures that the spark discharge can occur efficiently while avoiding excessive wear on the electrodes and achieving precision in material removal. A smaller gap leads to higher precision, while a larger gap can affect machining accuracy and efficiency.
