Programming example
A machine has six channel axes called XX, YY, ZZ,
U, V, W. The basic setting of the geometry axis
configuration in the machine data is:
Channel axis XX = 1st geometry axis (X axis)
Channel axis YY= 2nd geometry axis (Y axis)
Channel axis ZZ = 3rd geometry axis (Z axis)

7.8 Switchable geometry axes, GEOAX
810D 840Di
Basic configuration of the geometry axes is active.
All axes to position 0 in rapid traverse.
Channel axis U is the first (X), V is the second (Y), W is
the third geometry axis (Z).
Channel axis XX is the first (X), ZZ is the third geometry
axis (Z). Channel axis V remains the second geometry
axis (Y).
Full circle in the X, Y plane. Channel axes XX and Y
traverse.
Channel axis W becomes the second geometry axis (Y).
Full circle in the X, Y plane. Channel axes XX and W
traverse
Reset to initial setting
Channel axis U is the first (X), V is the second (Y), W is
the third geometry axis (Z).
Channel axes U, V, W each travel to position 10, XX as
the auxiliary axis travels to position 25.
V is removed from the geometry axes group. U and W
are still the first (X) and third geometry axis (Z). The
second geometry axis (Y) remains unassigned.
Channel axis U remains the first (X), V becomes the
second (Y) and W becomes the third geometry axis (Z).
V becomes the third geometry axis (Z), W is overwritten
and therefore removed from the geometry axes group.
The second geometry axis (Y) is still unassigned.
