W5: 3D tool radius compensation
19.2 Circumferential milling
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).
Special case
Intermediate blocks without traversing and orientation motions are executed at the
programmed positions, e.g. auxiliary functions.
Example:
N70 X60
N75 M20
N80 A3=1 B3=0 C3=1
N90 Y60
Blocks N75 and N80 are executed after N70. The circle block is then executed with the
current orientation.
