7.13 Replaceable geometry axes (GEOAX)
Example: geometry axis configurations for 6 channel axes
A machine has six channel axes called XX, YY, ZZ, U ,V ,W. The basic setting of the
geometry axis configuration via 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)

;The basic configuration of the geometry axes is effective.
;All the axes in rapid traverse to position 0.
;Channel axis U becomes the first (X), V the second (Y), W the third
;geometry axis (Z).
;Channel axis XX becomes the first (X), ZZ the third geometry axis (Z).
;Channel axis V stays as the second geometry axis (Y).
;Full circle in the X, Y plane. Channel axes XX and V 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 state
;Channel axis U becomes the first (X), V the second (Y), W the third
;geometry axis (Z).
;Channel axes U, V, W each traverse to position 10, XX as the special
;axis traverses to position 25.
;V is removed from the geometry axis grouping.
;U and W are still the first (X) and third geometry axis (Z).
;The second geometry axis (Y) remains unassigned.
;Channel axis U stays the first (X), V becomes the second (Y),
;W stays the third geometry axis (Z).
;V becomes the third geometry axis (Z), which overwrites W and thus
;removes it from the geometry axis grouping. The second geometry
;axis (Y) is still unassigned.
