1. The process of metal cutting.

The process of cutting metal from the workpiece blank by the tool is the process of metal cutting. Formation and types of cutting: banding, crushing, unit, chipping. The first three process plastic materials. The latter processes brittle materials. C-chip cutting is best.

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.

4. What kind of iron filings do you want to get when processing steel parts on book lathes?

5. Iron filings are mainly transmitted through small iron and surrounding media.
