Question:-
Consider the following statements:
The strength of a single point cutting tool depends upon
1. Rake angle
2. Clearance angle
3. Lip angle
Which of these statements are correct?
Option (A)
1 and 3
Option (B)
2 and 3
Option(C)
1 and 2
Option(D)
1,2 and 3
Correct Option:
(D)
Question Solution:
If back rake angle increases, the tool becomes more pointed and clearance angle prevents rubbing action.
Increases in lip angle signifies the decrement of positive rake angle, so strength increases
