Oblique Cutting: When the chip does not flow on orthogonal plane i.e chip deviates from orthogonal plane then it is called oblique cutting.
Basic Difference Between Orthogonal and Oblique Cutting: in oblique cutting inclination angle(lamda) have some value but in orthogonal cutting there is no lamda i.e lamda=zero.
Causes of orthogonal cutting:
- Restricted cutting effect.
- tool nose radius-ing.
- inclination angle (Lamda not equal to zero).
