Orthogonal Cutting and Oblique Cutting

Orthogonal Cutting and Oblique Cutting

Depending upon the direction of a cutting tool, forces and feed angle difference between orthogonal cutting and oblique cutting can be identified.

Orthogonal Cutting:

Orthogonal cutting is a type of metal cutting angle in which the direction of the cutting tool is perpendicular to the cutting edge. In orthogonal cutting operation, feed is at 90 degrees and it develops only two types of forces which are cutting force and thrust force which represents the 2-D cutting action.

In orthogonal cutting operation, there is a chance of chips weld over the cutting tool, due to this factor, the life of the cutting tool is shorter than the oblique cutting tool. 

Oblique Cutting :

In the oblique cutting tool, the direction of the cutting action is not perpendicular to the cutting edge, cutting edge makes an oblique angle with the cutting direction.

In Oblique cutting operation, there is no welding occurs on the tip of the tool. this factor helps to increases the life of the cutting tool. Due to the feed develops an oblique angle there is an extra force created which is cutting force, thrust force, and radial force. these forces represent the 3-D cutting action.
