W5: 3D tool radius compensation

19.4 Selection/deselection of 3D TRC

19.4 Selection/deselection of 3D TRC
The following commands are used to select/deselect 3D tool radius compensation for
circumferential milling or face milling:
• CUT3DC (circumferential milling)
• CUT3DFS (face milling)
• CUT3DFF (face milling)
• CUT3DF (face milling)
19.4.1

Selection of 3D TRC

CUT3DC
3D radius compensation for circumferential milling (only when 5-axis transformation is active).
CUT3DFS
3D tool offset for face milling with constant orientation. The tool orientation is determined by
G17 - G19 and is not influenced by frames.
CUT3DFF
3D 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.
CUT3DF
This programming command selects the 3D tool offset for face milling with change in
orientation (only when 5-axis transformation is active).
TRC selection
The program commands used to select 3D TRC are the same as those for 2D TRC. G41/G42
specify the compensation on the left or right in the direction of motion (the response on
selection of G41 and G42 for 3D face milling is identical). Tool radius compensation is
deactivated with G40. The approach response is always controlled with NORM. Activation must
be in a linear block.
