For me there is...If I want to top both the X and Y travel temporarily
while one or more of the other axis are doing some work, I'd call that a
"pause". For instance...suppose I need to mill a pocket and/or other
contours in the top of a part and want to drill some holes along one side
and machine a curved slot along the other side.

When I got to a predetermined point along the Y axis while milling the top,
I could "pause" for drilling a hole, release the pause, continue milling the
top, pause, drill a hole, etc. some where along the Y and/orX motion I could
pause and then operate a the turret of the third spindle for cutting that
curved slot.

Granted, not many people would NEED a complete 12 axis system like this but
it would be nice to have it available.
Actually I can envision a custom design that would allow the "lathe head" to
move up and down along the Z axis and back and forth along the X axis.
Renaming these to conventional X and Y for convience and installing an
identical system in lieu of a tailstock and installing a forth one
perpendicular to the lathe bed and installing a rotary table on top of the
table would provide a machining center that would allow conventional 3axis
milling of the top of a part as well as all for sides in one set up. This
would be a lot quicker for machining purposes than some of the machines I've
done jig and fixture work on which required four parts to be mounted (in
different positions) on a table inorder to machine the part. After each
cycle, the finished part was removed, the other parts moved and a new part
added.
Kind of time consuming!

Good point...I certainly would want to be able to do threading!
