Assertion (A) : The ratio of uncut chip thickness to actual

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

Assertion (A) : The ratio of uncut chip thickness to actual chip thickness is always less than one and is termed as cutting ratio in orthogonal cutting.
Reason (R) : The frictional force is very high due to the occurrence of sticking friction rather than sliding friction.

1. Both A and R are true and R is the correct explanation of A
2. Both A and R are true but R is not a correct explanation of A
3. A is true but R is false
4. A is false but R is true

Correct Option: C

Sliding friction is very higher
