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: Understand the mechanisms of material removal in different machining processes.
- Chemical Machining (A) involves material removal by corrosive action (II).
- Electro-Machining (B) involves fusion and vaporization due to electrical energy (I).
- Electro-chemical discharge Machining (C) involves ion displacement (IV), which is due to electrochemical processes.
- Ultrasonic Machining (D) involves erosion by high-frequency vibrations (III).
Step 2: Conclusion The correct matching is:
- (A) Chemical Machining → (II) Corrosive
- (B) Electro-Machining → (I) Fusion and vaporization
- (C) Electro-chemical discharge Machining → (IV) Ion displacement
- (D) Ultrasonic Machining → (III) Erosion
Final Answer: \[ \boxed{(A) (I), (B) (II), (C) (IV), (D) (III)} \]
