I saw a very high speed machining center at a trade show. Forget the
name, but it used a carousel sorta like a Brother or Fanuc RoboDrill.
When the tool came out from under the chip shield, it was suddenly just
THERE, 50 thou or so above the part. If there was a screwup in offsets
or something of that nature, the crash would be over and done with
before the brain could fully register what had just happened.

Here's one stellar example...

"First Law of Leftist Debate
The more you present a leftist with factual evidence
that is counter to his preconceived world view and the
more difficult it becomes for him to refute it without
losing face the chance of him calling you a racist, bigot,
homophobe approaches infinity.

This is despite the thread you are in having not mentioned
race or sexual preference in any way that is relevant to
the subject." Grey Ghost
