FZ - (only for G Depth infeed rate – (only for axis-by-axis approach strategy)
code)
FS Chamfer width for chamfering - (only for chamfering machining)
ZFS Insertion depth of tool tip (abs or inc) - (for machining only)
* Unit of feedrate as programmed before the cycle call
Note
Cylinder surface transformation with slot side compensation
For cylinder surface transformation with selected slot side compensation and
approach/retraction in quadrant or semi-circle, the approach/retraction radius must be
greater than "Offset to programmed path – tool radius".

Contour pocket/contour spigot (CYCLE63/64)

Contours for pockets or islands
Contours for pockets or islands must be closed, i.e. the starting point and end point of the
contour are identical. You can also mill pockets that contain one or more islands. The islands
can also be located partially outside the pocket or overlap each other. The first contour you
specify is interpreted as the pocket contour and all the others as islands.
Automatically calculating/Manually entering the starting point
Using "Automatic starting point" you have the option of calculating the optimum plunge point.
By selecting "Manual starting point", you define the plunge point in the parameter screen.
If the islands and the miller diameter, which must be plunged at various locations, are
obtained from the pocket contour, then the manual entry only defines the first plunge point;
the remaining plunge points are automatically calculated.
Contours for spigots
Contours for spigots must be closed, i.e. the starting point and end point of the contour are
identical. You can define multiple spigots, which can also overlap. The first contour specified
is interpreted as a blank contour and all others as spigots.
