To be honest, these machines do scare me a little bit. I know what they can do if you are not careful. Watch videos and take note of how many of those people have pretty bunged up hands. Especially the knuckles. A spinning lathe chuck contacting your knuckles would be a bad day for you. With CNC machinery, I would be REALLY worried that I might accidentally program in a command set that instructs the machine to
KILL THE HUMAN WHEN HE ISN'T LOOKING.
