2.3 Coordinate systems
2.3.1 Overview
Cartesian coordinate systems
DIN 66217 stipulates that machine tools must use right-angled, rectangular (Cartesian)
coordinate systems. The positive directions of the coordainate axes are determined using
the "Right Hand Rule". The coordinate system is related to the workpiece and programming
takes place independently of whether the tool or the workpiece is being traversed. When
programming, it is always assumed that the tool traverses relative to the coordinate system
of the workpiece, which is intended to be stationary.
