Question

In Ultrasonic Machining, the material is removed by:

• A. Anodic dissolution
• B. Thermal melting
• C. Abrasive action
• D. Electrochemical oxidation

Hint:

Ultrasonic machining is particularly useful for materials that are hard or brittle, as it relies on abrasive action rather than traditional cutting methods.

Answer 1

The Correct Option is C

In ultrasonic machining, material removal occurs through abrasive action. High-frequency ultrasonic vibrations are used to drive abrasive particles against the workpiece, causing micro-cutting or erosion at the surface. This process is effective for brittle materials that are hard to machine using traditional cutting methods. Anodic dissolution, thermal melting, and electrochemical oxidation are related to other processes like electrochemical machining (ECM) or thermal machining, not ultrasonic machining.
