Example 2: Changing over the geometry axes for six channel axes
A machine has six channel axes with the names XX, YY, ZZ, U, V, W.
The basic setting of the geometry axis configuration via 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)

Comment
; Channel axis Z1 acts as 3rd geometry axis (Z).
Comment
; The basic configuration of the geometry axes is ef-
fective.
; All axes in rapid traverse to position 0.
; Channel axis U becomes the first (X), V the second
(Y)
; and W the third geometry axis (Z).
; Channel axis XX becomes the first (X), ZZ 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 V traverse.
; Channel axis W becomes the second geometry (Y).
; Full circle in the X/Y plane. Channel axes
; XX and W traverse.
; Reset to the initial state.
; Channel axis U becomes the first (X), V the second
; (Y) and W the third geometry axis (Z).
; Channel axes U, V, W each traverse to
; position 10. XX as special axis traverses to posi-
tion 25.
; V is removed from the geometry axis group.
; U and W remain the first (X) and third
; geometry axis (Z).
; The second geometry (Y) axis remains unassigned.
; Channel axis U remains the first (X), V becomes
; the second (Y), W remains the third geometry axis
(Z).
; V becomes the third geometry axis (Z), whereby W
; is overwritten and therefore removed from the geom-
etry
; axis group. The second geometry axis (Y)
; still remains unassigned.
