Overview

Definitions
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.
