The Lathe: Oblique & Orthogonal Cutting

Question 1

What forces does orthogonal cutting consist of?

Answer 1

Orthogonal cutting has two forces, the tangential and axial force acting on the cutting tool.

Question 2

What is oblique cutting?

Answer 2

Oblique cutting consists of a three force system. The radial force is caused by the plan approach angle on the cutting tool. As the radial force increases, the axial force decreases.

Question 3

In oblique cutting, when the radial force increases, does the axial force increase or decrease?

Answer 3

As the radial force increases, the axial force decreases.

Question 4

In oblique cutting, what is the radial force caused by?

Answer 4

The radial force is caused by the plan approach angle on the cutting tool.
