The principle of material removal in Electrochemical machining is

1. Fick's law
2. Faraday's laws
3. Kirchhoff's laws
4. Ohm's law

Correct answer: Faraday's laws

Solution

Faraday's laws govern the amount of material removed during electrochemical machining by relating the mass of the material removed to the electric charge passed through the electrolyte, making them fundamental to the process.
