Pm = Pe*ηm/Zw
This formula uses 4 Variables
Variables Used
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.
Electrical Power Available for Machining - (Measured in Watt) - Electrical Power Available for Machining is defined as the maximum power that can be input for a Machining Operation.
Overall Machining Efficiency - Overall Machining Efficiency is defined as the product of all efficiencies, in each step of power transfer in Machining Operation.
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.
STEP 1: Convert Input(s) to Base Unit
Electrical Power Available for Machining: 14 Kilowatt --> 14000 Watt (Check conversion here)
Overall Machining Efficiency: 0.85 --> No Conversion Required
Metal removal rate: 0.16 Cubic Meter per Second --> 0.16 Cubic Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Pm = Pem/Zw --> 14000*0.85/0.16
Evaluating ... ...
Pm = 74375
STEP 3: Convert Result to Output's Unit
74375 Watt -->74.375 Kilowatt (Check conversion here)
FINAL ANSWER
74.375 Kilowatt <-- Rate of Energy Consumption during Machining
(Calculation completed in 00.020 seconds)
