Formation of cutting forces

Deformation and friction

Main cutting force, radial cutting force, axial cutting force.

1. When the brittle material is cut, it will crack.

2. The material can maintain its hardness under high temperature is abrasion resistance.

3. The main factor that affects the cutting temperature in the amount of cutting is the cutting speed.
