Note
The commands are modally effective and written in the same group asCUT2D and CUT2DF.
The command is not deselected until the next movement in the current plane is performed.
This always applies for G40 and is independent of the CUT command.
Intermediate blocks are permitted with 3D tool radius compensation. The definitions for 2 1/
2D tool radius compensation apply.
Supplementary conditions
• G450/G451 and DISC
A circular block is always inserted at out corners. G450/G451 have no significance.
The DISC command is not evaluated.

Activation of 3D radius offset for circumferential milling
3D tool offset for face milling with constant orientation.
The tool orientation is determined by G17 - G19 and is not
influenced by frames.
D tool offset for face milling with constant orientation. The
tool orientation is the direction defined by G17 - G19 and,
in some case, rotated by a frame.
3D tool offset for face milling with orientation change (only
with active 5-axes transformation).
To deactivate: Linear blockG0/G1 with geometry axes
