... passes outside the cutting wedge of the cutter, the chips after deformation come out of contact with the cutter and curl freely.

If the normal passes inside the cutting wedge of the cutter, then the chips cannot move freely, because they collide with the front surface of the cutter and are additionally ...

... additionally deformed.

Due to the chip pressure on the cutter and the high temperature, the particles of the deformable metal are inhibited.

The growth is formed most intensively when working with plastic metals.

Then the joint or drain chips are obtained.

When processing brittle metals, such as cast iron or bronze, the growth is not retained on the cutter.

... formation of growths.

The cutting speed has a great influence on the formation of the growth.

When processing carbon steel at a speed of 20-30 meters per minute, intensive growth formation occurs.

A sample of an incisor with a similar growth.

At lower speeds, the temperature in the cutting zone is insufficient ...

... insufficient for welding deformed metal particles, so no build-up is formed.

When working at high speeds, the temperature in the cutting zone increases significantly, as a result of which the growth becomes plastic and practically disappears.

A thin over-incisor layer is formed.

... the gear ratio.

Metal processing on a lathe is carried out in two coordinated movements.

The main movement is the rotation of the part.

... the control handle.

For threading on a lathe, it is necessary that the cutter receives a longitudinal displacement equal to the thread pitch for each revolution of the spindle, i.e. the speed of the longitudinal movement of the cutter must be consistent with the spindle rotation speed.
