Yes and me too. I was?taught many years ago at
college and confirmed later by a manufacturer, that all axis relate to the
workholder. Consider the lathe, the spindle axis holds the work. Now a vertical
milling machine, the spindle holds the cutting tool, but so does a horizontal
milling machine and the spindle is parallel to the bed!? Never mind slant
bed machines, multi-axis machining centres etc. So the Z axis move towards
and/or away from the workholder. The X & Y axis move across the workholder
at right angles to each other. Not all 3 need to be used eg centre lathe and
some machines have 4 or more axis eg multi-spindle machining centres. However,
as we are not all professional machining companies, we don't need to get our
knickers in a twist over it.
