A cartoon explaining the heat distribution during cutting.

When the cutting speed increases, most of the heat goes away with the chips.

The role of the coolant in the removal of heat into the environment.

... takes place.

In all cases, the greatest acting force is the circumferential cutting force.

It acts on the surface of the cutter and carries out the chip formation process.

According to the circumferential cutting force, the main and responsible nodes of the machine are calculated.

According to the circumferential ...

... the metal, chip shrinkage decreases, but the stress in the chip formation zone increases.

Depending on the predominance of these phenomena, the cutting forces either decrease or increase accordingly.

When turning cast iron, the predominant effect on the cutting forces is a decrease in chip shrinkage, ...

... predominant influence on the cutting forces is exerted by an increase in the stress in the chip formation zone, here the cutting forces will increase.

The cutting forces are affected by the cross-sectional area of the chip being cut.

A cartoon explaining this process.

Graph of the dependence of the cutting ...

... formation of chips.

The chip moves along the normal to the shear plane.

If the normal 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 ...

... move freely, because they collide with the front surface of the cutter and are additionally deformed.

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