Machining Power Calculator and Formulas
Assuming the efficiency is 100%, the power required to remove the material is the same as the power used by the machine’s motor. Each machine has a maximum power limit that it can handle. Therefore, it is helpful to calculate the power required to perform a machining operation such as milling or turning and compare it to our machine’s ability.
