Manufacturing processes

1. Explain the factors involved in selecting the appropriate type of abrasive for a particular grinding operation.
2. What are the consequences of allowing the temperatures to rise during grinding? (Q. 25.38).
3. What are the implications of using a smaller abrasive grain size (higher grit number) in a bonded grinding wheel?
4. Why are speeds so much higher in grinding than in cutting?
5. In which of the manufacturing activities in industry is the wire EDM process most applicable?
6. Which of the advanced machining process causes thermal damage? What is the consequence of such damage to work pieces?
7. Describe your thoughts regarding the laser-beam machining of non metallic materials. Give several possible applications, including their advantages as compared to other processes.
8. Does EDM affect the fatigue strength of cold worked metals? Explain.
