Single pos. A longitudinal slot is milled at the programmed position (X0, Y0, Z0).
Pos. pattern Several longitudinal slots are milled in a position pattern (e.g. full circle, pitch circle,
matrix, etc.).
The positions refer to the reference point:
X0 Position in X direction (single position only), abs. or inc.
Y0 Position in Y direction (single position only), abs. or inc.
Z0 Workpiece height (single position only), abs. or inc.
W Slot width
L Slot length
α 0
Angle of rotation
Z1 Depth of the slot (not for chamfer)
DXY Max. infeed in plane (XY direction)
Alternatively, you can specify the plane infeed as a %, as a ratio
(mm) to milling cutter diameter (mm). (not for chamfer)
DZ Max. depth infeed (Z direction) (not for chamfer)
FS Chamfer width (for chamfer only), inc.
ZFS Insertion depth tool tip (for chamfer only), abs. or inc.
UXY Finishing allowance in plane (slot edge) (not for chamfer)
ZU Finishing allowance in depth (slot base) (not for chamfer)
Insertion It can be inserted vertically over slot center (Mi) or with oscillating motion (Pe):
Center=Insert vertically in center of longitudinal slot:
The tool is inserted to infeed depth in the pocket center.
Note: This setting can be used only if the cutter can cut across center.
Oscillation=Insert with oscillation along center axis of longitudinal slot:
The cutter center point oscillates along a linear path until it reaches the depth infeed.
When the depth has been reached, the path is traversed again without depth infeed
in order to remove the slope caused by insertion.
FZ Depth infeed rate (for insertion in center only)
EW Insertion angle (for oscillation only)
