Question

Match List-I with List-II

Choose the correct answer from the options given below:

• (A) (I), (B) (II), (C) (III), (D) (IV)
• (A) (I), (B) (III), (C) (II), (D) (IV)
• (A) (I), (B) (II), (C) (IV), (D) (III)
• (A) (II), (B) (IV), (C) (I), (D) (III)

Hint:

Different machining processes use different mechanisms to remove material, such as corrosion, fusion, ion displacement, and erosion.

Answer 1

The Correct Option is C

Step 1: Material Removal Mechanisms in Machining Processes
- Chemical Machining (A): Material removal via corrosive action (II).
- Electro-Machining (B): Material removal via fusion and vaporization due to electrical energy (I).
- Electro-chemical discharge Machining (C): Material removal via ion displacement (IV) through electrochemical processes.
- Ultrasonic Machining (D): Material removal via erosion by high-frequency vibrations (III).
Step 2: Summary of Matching
- (A) Chemical Machining → (II) Corrosive Action
- (B) Electro-Machining → (I) Fusion and Vaporization
- (C) Electro-chemical discharge Machining → (IV) Ion Displacement
- (D) Ultrasonic Machining → (III) Erosion
Final Answer: \[ \boxed{(A) (II), (B) (I), (C) (IV), (D) (III)}\]
