Question

Which of the following statements are true for Electro-Chemical Machining (ECM)?

• A. (1), (2) and (3)
• B. (2), (3) and (4)
• C. (1), (3) and (4)
• D. (1), (2) and (4)

Hint:

ECM is a non-traditional machining process that excels in working with hard materials, as it does not rely on mechanical cutting forces.

Answer 1

The Correct Option is D

In Electro-Chemical Machining (ECM), the process is capable of machining metals and alloys regardless of their strength and hardness. This is one of ECM's key advantages. Additionally, no cutting forces are involved in ECM, as material removal occurs through electrochemical erosion rather than mechanical cutting. Dielectric fluid is also used in ECM to help in the process of material removal and cooling. The statement about erosion taking place as a reverse process of electroplating is incorrect in the context of ECM, as ECM involves the anodic dissolution of material, not the reverse of electroplating.
