To All:
Is there a difference between Fixture Offsets, Work Offsets, and Work
Coordinates Systems? I'm looking for a consensus here, so even if you
believe someone else's answer is correct, please add your own comments.
Thank you.

It is all good.
I use them all when I speak in terms of "work origins"

Yes and no, the terms work offset and fixture offset in general refer to
the same thing. The work coordinate system is something different entirely.
There are all sorts of controls and many use different terminology. On a
Fanuc, you won't find the term "Work offset" in any manual. You'll find
"Fixture offset" used in an "M" (mill) control manual. And you'll find
"work shift" in a lathe ("T") manual.

Dan:
The "work coordinate system" seems to be a term used differently in a
lathe vs. a mill.

Not really. When Cliff implied there was a difference between Fixture
Offsets and Work Offsets he was wrong, since they BOTH refer to the
G54-G59 offsets in the control.

Bob,
Not really. What I was getting at is that the work coordinate system is
just that. It is the coordinate system that you set up inrelation to the
work that you are doing. It can be set by G92 (or G50) it can also be
changed or shifted by using G54-G59. Or you can do nothing at all, in
which case you would be working in the machine's coordinate system.
The work coordinate system is different than "fixture offsets" since it
is possible to set one up without using G54-G59.

He could, but how many would believe him? He's cried Wolf...err bait,
too many times.

"True but now Cliff will just say he knew that from the begriming and
it was just jb bait."
And in the mean time Cliff will ignore machining topics such as what
has been posted in the soft jaw thread, etc.
