CUT2D 1 2½D TRC + m x
CUT2DF 2 2½D TRC relative to the current frame (inclined plane) + m
CUT3DC 3 3D TRC for circumferential milling + m
CUT3DF 4 3D TRC for face milling with change in orientation + m
CUT3DFS 5 3D TRC for face milling with constant orientation. The
tool orientation is defined by G17 - G19 and is not
influenced by frames.
+ m
CUT3DFF 6 3D TRC for face milling with constant orientation. The
tool orientation is the direction defined by G17 - G19
and, in some cases, rotated by a frame.
+ m
CUT3DCC 7 3D TRC for circumferential milling taking into account
a limitation surface with 3D radius compensation: Con‐
tour on the machining surface
+ m
CUT3DCCD 8 3D TRC for circumferential milling taking into account
a limitation surface with a differential tool on the tool
center-point path: Infeed to the limitation surface
+ m
CUT2DD 9 2½ D TRC in relation to the differential tool + m
CUT2DFD 10 2½D TRC in relation to a differential tool relative to the
current frame (inclined plane)
