Consider the following statements with respect to the relief

Home » Materials Science and Manufacturing Engineering » Materials Science and Manufacturing Engineering Miscellaneous » Question

Consider the following statements with respect to the relief angle of cutting tool:
1. This affects the direction of chip flow.
2. This reduces excessive friction between the tool and workpiece
3. This affects tool life
4. This allows better access of coolant at the tool-workpiece interface
Which of the statements given above are correct?

1. 1 and 2
2. 2 and 3
3. 2 and 4
4. 3 and 4

Correct Option: B

Provides flank inclination to relief from elastic recovery so less rubbing action, hence low flank wear.
