This set of Manufacturing Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Milling Methods”.
1. In which of the following milling method cutters rotate in direction opposite to that in which work is fed?
a) Up milling
b) Climb milling
c) Down milling
d) None of the mentioned
View Answer
Explanation: In up milling cutters rotate in the direction opposite to that in which work is fed.
2. In which of the following milling method chip thickness increase gradually?
a) Up milling
b) Climb milling
c) Down milling
d) None of the mentioned
View Answer
Explanation: In up milling chip thickness increase gradually whereas in down milling chip thickness decreases gradually.
3. In which of the following milling method chip thickness decrease gradually?
a) Up milling
b) Conventional milling
c) Down milling
d) None of the mentioned
View Answer
Explanation: In down milling, chip thickness decreases gradually whereas in up milling chip thickness increase gradually.
4. In which of the following milling method chip thickness is nearly zero at the start of cut?
a) Up milling
b) Climb milling
c) Down milling
d) None of the mentioned
View Answer
Explanation: In up milling, chip thickness increases gradually from zero at the start of cut to the maximum value at the end.
5. In which of the following milling method chip thickness is maximum at the end of cut?
a) Up milling
b) Climb milling
c) Down milling
d) None of the mentioned
View Answer
Explanation: In up milling chip thickness increase gradually whereas in down milling chip thickness decreases gradually.
6. In which of the following milling method chip thickness is nearly zero at the end of cut?
a) Up milling
b) Conventional milling
c) Down milling
d) None of the mentioned
View Answer
Explanation: In down milling chip thickness decrease gradually from maximum at the start of cut to the zero at the end.
7. Which of the following will result in best surface finish of job?
a) Up milling
b) Conventional milling
c) Down milling
d) None of the mentioned
View Answer
Explanation: Down milling gives better surface finish than up milling. In down milling chip thickness decrease gradually from maximum at the start of cut to the zero at the end.
8. In which of the following methods work piece will have a tendency to be pulled up?
a) Up milling
b) Climb milling
c) Down milling
d) None of the mentioned
View Answer
Explanation: In up milling cutters rotate in the direction opposite to that in which work is fed. Upward force is acted on work piece by tool.
9. In which of the following methods of milling there would be less radial pressure on the arbor?
a) Up milling
b) Conventional milling
c) Down milling
d) None of the mentioned
View Answer
Explanation: Down milling generates less radial pressure. In down milling, chip thickness decrease gradually from maximum at the start of cut to the zero at the end.
10. Which of the following milling operation will require lower force of cut?
a) Up milling
b) Climb milling
c) Down milling
d) None of the mentioned
View Answer
Explanation: In up milling large force is generated due to the opposite motion of tool and work piece. In up milling chip thickness increase gradually whereas in down milling chip thickness decreases gradually.
