Yes, you've given us little reason to doubt that
you're a legend in your own mind.
I don't have to measure up to your unsolicited, unqualified,
unprofessional, E-1 grade bullshit assessments, do I, asswipe?
I was using coordinate measuring machines on turbine blades for GE
Evendale before they were even used in machine shops all over the
world (1971) I knew 100 thousandth inch tolerances on machine tools
before you knew what a hundred thousandth inch was.
I've seen "One thousandth inch diameter" drills claimed to be "the
world's smallest drill" by Russia get sent back to them with a 3 ten
thousandth inch hole drilled into the shaft.
I have recently made machinery that actuates piezo motors of the
linear variety at kHz rates to the tune of tens of microns...
accurately. To the point of being able to cut optical quality
surfaces on a single pass that do not need further finishing, and can
even cut a square peg on a rotating shaft in a lathe at such
accuracies and rates.
Yes, that's complex part milling and cutting on a rotating lathe
spindle where the cutting head has nanometer-precision accuracy, and
kHz translation rates and speeds. The piezo stack has to be excited
by several hundred volts at a couple kW, so that has to be one clean
high power "audio" amp, eh? The stack generates several hundred
pounds of force in the tightly controlled, nanometer precise linear
translations it performs. The computer adjusts the entire system for
the physical backlash contained in the mechanics of the machinery.
Hell, I even made one for LLNL. Naaaahhh... I don't know what I'm
doin'... at all. Right. We are up to 2.5kW now with a full 2mm
action.
Next quarter, we will make a 2.5 kW RF amplifier for FM band that
will replace a 2kW competitor's model in a smaller space with a much
higher power factor! Naaah... I sit around drinking beer. I didn't
do any of that stuff.... Sure...
