Project ForgeMatch the following non-traditional machining processes with the corresponding material removal mechanisms: P: Chemical machining, Q: Electro-chemical machining, R: Electro-discharge machining, S: Ultrasonic machining. Mechanisms: 1. Erosion, 2. Corrosive reaction, 3. Ion displacement, 4. Fusion and vaporization.
- P-2, Q-3, R-4, S-1
- BP-2, Q-4, R-3, S-1
- CP-3, Q-2, R-4, S-1
- DP-2, Q-3, R-1, S-4
Explanation
Chemical machining removes material via a corrosive chemical reaction (P-2). Electro-chemical machining removes material via anodic ion displacement/dissolution (Q-3). Electro-discharge machining removes material via spark-induced fusion and vaporization (R-4). Ultrasonic machining removes material via abrasive erosion from the vibrating tool (S-1).
