Milling Horsepower Calculator. Calculate the horsepower required for a milling operation based on the feed rate and depth of cut, which are used to determine the material removal rate (or metal removal rate). Also required is the unit power, which is a material property describing the amount of power required to cut that material.

So even if the spindle power meter graph shows 100 % during these cutting periods, the heat generation is less. When power varies like this, we take the root mean squared (RMS) value as the the equivalent uniform power. For 25, 50 and 75 % duty cycles, the RMS power is roughly 45 %, 70 % and 86 % respectively of the peak power consumption.

During milling operation, the cutting force is measured directly using the force sensor (dynamometer) for obtaining the spindle power, and machine tool power consumption is measured in-line, simultaneously for accomplishing of total power which includes idle, cutting and auxiliary power components.
The highest value of total energy consumption in milling (97 kJ) has been obtained by choosing the minimum depth of cut of the experimental campaign, whereas the lowest one (28 kJ) by choosing the maximum depth of cut. A depth of cut of 0.9 mm and a spindle speed of 2500 rev/min led to minimizing total energy consumption in milling.
In this work, Data Dependent Systems (DDS), a stochastic modeling and analysis technique, was applied to study spindle motor energy consumption during a hard milling operation.
