1.2.1 Coordinate system
When machining a workpiece on a lathe, one basically uses a right-
angled coordinate system. This consists of the three coordinate axes
X, Y, and Z which are parallel to the machine axes. The coordinate
axis Y does not have to be set up. Spindle axis Z is an independently
rotating axis and is designated with the letter C.
The positions of the coordinate system and the machine zero depend
on the type of machine used.
