In physics, power is defined as the amount of energy transferred per unit of time. In the case of CNC machining, the electrical network passes energy to the spindle's electric motor, which passes it to the cutting tool. The cutting tool uses this energy to extract material from a workpiece. Assuming the efficiency is , the power …
