4.1 Coordinate system and reference point
The traversing directions of a machine tool refer to a coordinate system assigned to the
traversing axes of the machine tool. A right-handed and right-angled coordinate system with
the axes X, Y, and Z is used. The coordinate system is assigned to the main axes of the
machine tool.
