Power Constraint
The power constraint supposes significance just in case of rough machining and therefore might be ignored in the case of finish machining. The power consumed, P throughout a turning operation might be expressed as:
Equation 1

This value of cutting power should not exceed the maximum power, Pmax available on the machine tool. In the above given expression, the value of particular cutting force is constant for a particular work material. Therefore, the expression for this constraint might be written as
Equation 2
Cp V ap f bp d c p ≤ Pmax
C = kc /60.1000. η
