Deselection of 3D TRC

Deselection
The 3D tool radius compensation function is deselected in a linear block G0/G1 with geometry
axes by means of G40.
Example:
Program code
N10 A0 B0 X0 Y0 Z0 F500
N20 T1 D1
N30 TRAORI(1)
N40 CUT3DC
N50 G42 X10 Y10
N60 X60
N70 G40 X100 Y0 Z20
N80 ...
Note
D0 is programmed via active tool radius compensation, so there is no selection. If no geometry
axis is programmed for the current plane in the block with the selection, no selection takes
place.

Constraints

Face milling
The following boundary conditions must be observed for the "3D tool radius compensation"
for face milling:
● Functions with higher-order geometry information cannot be used (e.g. compressor,
polynomial or spline interpolation).
● A "bottleneck detection" is not possible, and therefore the user is solely responsible.
● For traversing motion in the orientation direction of the tool, and alarm is displayed and
machining stopped.
