Metal cutting or commonly known as machining, is the most common phenomenon used in manufacturing industries. Every product, big or small, undergoes a machining process to get final product. So the knowledge of basic types of metal cutting are most important. If we talk about metal cutting two terms comes in our mind orthogonal and oblique.

In oblique cutting, the cutting edge makes an angle with the direction of motion. Oblique Cutting. Oblique cutting is a type of cuttings in which the cutting tool is at an oblique angle in the direction of the tool's motion. The chip flow in this cutting is not cutting edge. The tool has a longer cutting life than orthogonal cutting.
