# Difference between orthogonal and oblique cutting

### Orthogonal Cutting :-

Orthogonal cutting is a type of cutting in which the cutting tool is perpendicular to the direction of tool motion. In this cutting, the flow of chip is perpendicular to cutting edge. The tool has lesser cutting life in this type of cutting.

In Orthogonal cutting, the direction of flow of chip is perpendicular to the direction of movement of cutting edge.

### Oblique Cutting :-

Oblique cutting is a type of cutting in which cutting tool is at an oblique angle to the direction of tool motion. In this cutting, the flow of chip is not perpendicular to cutting edge. The tool has greater cutting life as compared to orthogonal cutting.

In Oblique cutting, the direction of flow of chip is not perpendicular to the direction of movement of cutting edge.

The main difference between orthogonal and oblique cutting is that in orthogonal cutting, cutting edge of tool is perpendicular to the direction of motion but in oblique cutting the cutting edge make an angle with direction of motion.

Apart from this , there are other difference which are stated below :-
