This formula uses 3 Variables
Variables Used
Machining Power - (Measured in Watt) - Machining Power is defined as the power required at the Tooltip to complete different Machining processes.
Metal removal rate - (Measured in Cubic Meter per Second) - Metal removal rate (MRR) is the amount of material removed per time unit (usually per minute) when performing machining operations such as using a lathe or milling machine.
Rate of Energy Consumption during Machining - (Measured in Watt) - Rate of Energy Consumption during Machining is the amount of energy transferred or converted per unit of time by the machine to the workpiece.
STEP 1: Convert Input(s) to Base Unit
Metal removal rate: 0.16 Cubic Meter per Second --> 0.16 Cubic Meter per Second No Conversion Required
Rate of Energy Consumption during Machining: 0.10792575 Kilowatt --> 107.92575 Watt (Check conversion here)

Machining Power = Metal removal rate*Rate of Energy Consumption during Machining
Pmachining = Zw*Pm

Reducing Machining Power

A Machine conserves energy when it isn't making chips, but profitability comes from maximizing the amount of a machine's metal-cutting time. Therefore, reducing cycle time is another method for reducing power use, and one way to achieve that is by machining at a high spindle speed.
