N10 TRAORI(1) ; Transformation on.
N20 TOFFON(Z) ; Activation of online tool length
compensation for the Z tool
direction.
N30 WHEN TRUE DO $AA_TOFF[Z]=10 G4 F5 ; A TLC of 10 is interpolated for the
Z tool direction.
...
N100 XOFFSET=$AA_TOFF_VAL[X] ;
ssigns actual compensation in the X
direction.
N120 TOFFON(X,-XOFFSET) G4 F5 ;
or the X tool direction, the TLC is
reduced back to 0.
Example 2: Deselect the tool length compensation
Program code Comment
N10 TRAORI(1) ; Transformation on.
N20 TOFFON(X) ; Activation of online tool length
compensation for the X tool
direction.
N30 WHEN TRUE DO $AA_TOFF[X]=10 G4 F5 ; A TLC of 10 is interpolated for the
X tool direction.
...
N80 TOFFOF(X) ; Position offset of the X tool
direction is deleted:
...$AA_TOFF[X]=0
No axis is moved.
The position offset is added to the
actual position in the Work
corresponding to the
actual orientation.
