Understanding Material Removal Processes
In manufacturing, various processes are employed for material removal. Each method corresponds to specific mechanisms of removing material, as outlined below:
1. Ultrasonic Machining (USM) - Mechanism Q
- Utilizes high-frequency vibrations to create micro-chipping.
- The abrasive grains are propelled by the ultrasonic waves, which contribute to the chipping process.
2. Electrical Discharge Machining (EDM) - Mechanism R
- Involves erosion due to electrical discharges.
- Sparks vaporize material and cause chipping, effectively removing it from the workpiece.
3. Powder Abrasive Machining (PAM) - Mechanism S
- Combines melting and partial vaporization of the material.
- Uses high-speed particles to melt and erode the surface of the workpiece.
4. Electrochemical Machining (ECM) - Mechanism T
- Operates through electrolysis, removing material via electrochemical reactions.
- This process is effective for intricate shapes and can achieve high precision.
5. Abrasive Jet Machining (AJMP) - Mechanism 2
- Involves throwing abrasive grains at high velocity to erode the surface.
- The impact causes chipping and erosion of the material.
Conclusion
Thus, the correct mapping of the processes to their mechanisms is:
- USM corresponds to Q (Chipping and erosion).
- EDM corresponds to R (Erosion due to vaporization).
- PAM corresponds to S (Melting and partial vaporization).
- ECM corresponds to T (Electrolysis).
- AJMP corresponds to 2 (Abrasive grain throwing and hammering).
Therefore, the correct answer is option C: 2 (USM) 4 (EDM) 5 (PAM) 3 (AJMP) 1 (ECM).
