You think I can't do that now? But there is one thing missing, a camera,
and a robot to take a measurement of a test cut, and then tell the proggy
how far off the zero mark it was. I'd need one arm to run the caliper, and
one arm to aim the camera at the caliper so I can read it.
But really, that is a poor excuse since I can buy cables that will let me
use the average $30 digital caliper by reading it out the calipers serial
port that is available by sliding a cover off the top right corner of the
caliper's display head. Your trivia factoid for the day...
The problem with a lathe is that there is no reliable method of advancing a
tool to the true centerline of the spindle and setting that to 0, plus or
minus .0001". There are no facilities that could be raised to establish
this 'zero' point, at least not with the required accuracy. One can
calibrate it so if you tell it what cutting tool is mounted, it can adjust
to match that tool, but what if the tool dulls and is replaced or
resharpened? So you may as well make the light test cut, measure it and
tell the lathe that the tool is now at 0.797" in radius or diameter, which
is not the same. The software has mode switches of course.

That too, but remembering all the (*&^% PW's to get to the machine from the
outside world would be a chore. Besides, I don't speak French, never got
far enough in school for that to be a required subject. So officially (my
record speaks for itself in broadcasting & electronics) I am a dummy with
an 8th grade education. People with a vested interest in higher education
simply do not understand that ones education can take place without the
confines of a school building.
