In cutting action,three type of zone are presents
1.Primary zone :
The most of part of energy is converted in to heat.
2.Secondary zone:
Heat generation due to rubbing between tool and chip.This also called deformation zone.
3.Tertiary zone:
Heat generated due to flank of tool and already machined surface.
So the highest temperature is located close to the shear zone.
