The method by which the orientation is changed at an outer corner is determined by the
program command that is active in the first traversing block of an outer corner.

Example:
N10 A0 B0 X0 Y0 Z0 F5000
N20 T1 D1
N30 TRAORI(1)
N40 CUT3DC
N50 ORIC
N60 G42 X10 Y10
N70 X60
N80 A3=1 B3=0 C3=1
N90Y60
N100 X10
N110 G40 X0 Y0
N120 M30
The circular motion and change in orientation are executed in parallel in block N80 (ORIC
active).
