Fundamental Geometrical Principles

1.1

Workpiece positions

1.1.1

Workpiece coordinate systems

In order that the machine or the control can work with the positions specified in the NC
program, these specifications have to be made in a reference system that can be transferred
to the directions of motion of the machine axes. A coordinate system with the axes X, Y and
Z is used for this purpose.
DIN 66217 stipulates that machine tools must use clockwise, right-angled (Cartesian)
coordinate systems.
