Example 2: Adaptation of the absolute G0 tolerances
The following absolute G0 tolerances should be preset in the machine data:
● G0 contour tolerance: 0.1
● G0 orientation tolerance: 1.0
These tolerances should be temporarily adapted in the part program:

Comment
; Compressor function COMPCAD
; The machine and setting data apply here.
; Machine data $MC_G0_TOLERANCE_FACTOR (e.g. =3) is ef-
fective here, i.e. a smoothing tolerance of:
$MC_G0_TOLERANCE_FACTOR * $MA_COMPRESS_POS_TOL
; A contour tolerance of 0.02 mm is applied starting
from here.
; From here, a G0 tolerance factor of 4 applies, i.e. a
contour tolerance of 0.08 mm.
