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, P_max 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

C_p V ^ap f ^bp d ^{c p}  ≤ P_max

C   =    kc /60.1000. η
