Question

Match the processes with their characteristics. Process Characteristics P: Electrical Discharge Machining 1. No residual stress Q: Ultrasonic machining 2. Machining of electrically conductive materials R: Chemical machining 3. Machining of glass S: Ion Beam Machining 4. Nano-machining

Process	Characteristics
P: Electrical Discharge Machining	1. No residual stress
Q: Ultrasonic machining	2. Machining of electrically conductive materials
R: Chemical machining	3. Machining of glass
S: Ion Beam Machining	4. Nano-machining

Correct answer (A) P-2, Q-3, R-1, S-4 Solution Let's match each process with its characteristic: P: Electrical Discharge Machining (EDM) is a non-conventional machining process used for electrically conductive materials, regardless of their hardness. So, P matches with 2. Q: Ultrasonic Machining (USM) is typically used for machining brittle materials like glass, ceramics, and carbides, using abrasive slurry. So, Q matches with 3. R: Chemical Machining (CHM) involves material removal by chemical dissolution. It is a stress-free process and generally leaves no residual stress on the workpiece. So, R matches with 1. S: Ion Beam Machining (IBM) uses a focused beam of ions to remove material at an atomic level, making it suitable for nano-machining and micro-fabrication. So, S matches with 4. Combining these, the correct match is P-2, Q-3, R-1, S-4. Therefore, option (A) is the correct answer. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
