BME-008 MACHINING TECHNOLOGY
Time 3 hours Maximum Marks: 70
Note: Attempt any five questions. All questions carry equal marks. Use of scientific calculator is permitted.
1. Which cutting tool will be best suited for mass production of aluminum parts Why?
A cutting tool cutting at 25 m/minute gave a life of 1 hour between regrinds when operating on roughing with mild steel. What will be its probable life engaged on light finishing Assume n 1/8 for
roughing and n 1/10 for finishing. 7+7
2. Explain the mechanism of chip formation.
Discuss the effect of tool angles on quality of metal machining. 7+7
3. How are the grains of abrasives classified
Is honing a material removal process What inaccuracies does the honing process eliminate? 7+7
4. Why do you observe sparks when the sharpening of scissors is done? Explain.
List the factors to be kept in mind while selecting a grinding wheel. 7+7
5. Explain metal spraying process with neat sketch.
In lapping process, what would be the consequence if the workplace is softer than the lap? 7+7
6. Under what conditions can abrasive machining be used? State the limitations of natural abrasives.
Explain the electroplating process with neat sketch. 7+7
7. Give possible technical and economical reasons why non-conventional machining processes are necessary.
Explain the laser beam machining process with neat sketch. 7+7
8. Why is chemical machining process a selective material removal process Explain.
How is the electrochemical machining process different from electroplating 7+7
