The milling process – definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round insert cutters ...
Power consumption was represented by cutting power of milling machine. The power meter and a computer were connected to the single-spindle milling machine. Measurement of cutting power was carried out by digital power meter METREL Power Q plus MI2392 (METREL D.D., Horjul, Slovenia) both in milling and idling conditions.
A domestic energy display works for a small machine (13amps or less in uk) about £14 I'm told, 3 phase is harder, unless your spindle is on one phase, but there is usually an ammeter on the pendant, most cnc machines have a graph these days (fanuc robodrill had a power monitor for tool wear etc, don't know if that was a standard thing)

However, what's much more important than spindle power is the actual performance relative to your specific application — in this case, milling titanium parts for dental implants. I've never seen the power consumption of the D5 spindle exceed 24% while milling titanium bars or custom abutments. In fact, it usually hovers around 14-16%.

The aim of the research was to optimize the cutting parameters for minimum surface roughness (Ra) and energy consumption (EC) using a CNC milling machine. At the same time, measurements of power indices (A) of both the spindle and the X -axis motors were carried out with the goal of improved chip removal as compared to literature studies.
In milling (say, face-milling or end-milling), one can measure the cutting power by using the following three approaches: (i) use a spindle mounted dynamometer to directly measure the cutting ...

Chip flow is a critical factor in milling cutter selection due to increases in spindle speeds, reduction in machine spindle power, and the increased use of machining centers as opposed to machines that perform milling exclusively. Chip flow affects power consumption, surface finish, and potential productivity levels in milling.

Power consumption during milling Here the power consumption of a main spindle and the feed drives is itemized. Example 1: Rough facing During rough facing with paraxial feed rate the feed motors have a mean power consumption of 200 W. The main spindle reaches it rated power at approx. 19 kW. Example 2: Circular pocket
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.
Most of the power is going to come from the vacuums, the spindle and your air compressor. So, for example, if you've got a 10hp spindle, two 20 hp vacuum pumps and you're using 10cfm air (from your 15hp compressor which puts out 50cfm) your max hp draw is 53. 1hp is about 750 watts - your wattage is about 40,000 watts or 40KW.
MRR = .200 x 1.64 x 19.5 = 6.4 in3/min. For horsepower at the motor (HPm), use formula: HPm = HPC/E. In determining horsepower consumption, "K" factors must be used. The "K" factor is a power constant that represents the number of cubic inches of metal per minute that can be removed by one horsepower.

S.Y. Nanal, A.R. Garde, in High Speed Spinning of Polyester and its Blends with Viscose, 2009 (f) Power cost About 60% of the power consumption of a spinning mill is at the ring frames, and the power cost is about 8% of sales. And power consumption at the ring frames is mainly because of the spindles and bobbins rotating at high speeds with ballooning yarns under tension.
