Hello Andy,
That is interesting, I should learn more about these coordinate
systems. From a math/geometry perspective there nothing that could
keep you from
translating, rotating (and even more weird transformations) a geometry
into a custom one. However in an implementation, of course, you'd have
to have a spot somewhere between the definition of an object (g code if
you will) and where the machine/tool actually moves. In some, not CC
related, simulations, that's actually done/used.
there probably is a list of what these coordinatesystems actually do?
(Now I am wondering, if I make a part, is there a coordinate system,
that would turn out the mirror image that part?)

It sounds like the coordinate systems in essence are the same, they
just have a different origin, for all the other parts, it's just the
same thing, just translated and/or rotated for another part?
Yes, and there is also only rotation about the axis supported.
(I did just find myself wondering if you could put a set of direction
cosines in UVW but then decided that there probably isn't much call
for that.)
