My big machine was never shut off, It was on for at least ten days and
maybe more.
I came to the workshop and swtiched the light on (two rows of industrial
double fluorescent), I noticed that the machine gave noise when the light
went on which has never happened before. I went to the machine which

If you are mainly planning on cutting aluminum I would suggest looking
into oil mist cooling instead of flood coolant.
Can anyone suggest me way to obtain cutting forces?

Very much so.
One hypothesis might be that the timing of a task relative to the
mains frequency might have changed with the restart.
it is also possibly possible that the behaviour appeared after a
counter wrap

Viesturs,
It depends what kind of machining you'll be doing - the forces in milling are
lower than those in drilling. Based on some axis motor testing I did a couple
years back, I would guess at a conservative estimate of around 250 lbs per
spindle horse power for the worst-case machining

Viesturs,
I was testing in Aluminum, but I think that for a given spindle HP your results
would be similar in other materials. If you're on an open loop machine it's
preferable to size the motors such that you stall the spindle before stalling
an axis motor because it's often an easier

Vibration consideration and rigidity are usually more limiting factors
in machining than HP. For example, a standard Bridgeport style mill
has a 1.5 hp motor. Most formulas give ambitious speed/feed/DOC vs hp
based on perfect stability. The forces required to cut are small
compared to the forces
Hi,
I wonder if LinuxCNC supports a rotated work-piece coordinate system?
I.E. I'd like to be able to place my work-piece anywhere on the table,
in any orientation and then somehow measure positions and orientation
and then be able to compensate both it so that I can run a my prepared job.
I'm

If you're only using small end mills, then the max axis force required is
simply just a bit more than the force required to snap the end mill. I would
think that a 6mm end mill wouldn't be capable of delivering 1.5 HP to a
workpiece.
That all depends on RPM. A 6 mm
