Machine coordinate system

The machine coordinate system comprises all the physically existing machine axes.
Reference points and tool and pallet changing points (fixed machine points) are defined in
the machine coordinate system.
Where the machine coordinate system is used for programming (this is possible with some
of the G functions), the physical axes of the machine are addressed directly. No allowance
is made for workpiece clamping.
