67Mechanics of Orthogonal Cutting
Conversion of this energy into heat occurs at the shear zone (E
s
) and the
friction at the tool–chip interface (E
f
). Therefore, E
c
= E
s
+ E
f
, where

where
E
c
is the rate of energy consumption during metal cutting (Nm/min)
E
s
is the rate of heat generation in the shear zone (Nm/min)
E
f
represents the rate of heat generation due to friction at the tool face
(Nm/min)

At the shear zone, the maximum temperature is generated as a result of the ...
