Parameter Description
FZ (only for G code) Depth infeed rate
Machining The following machining operations can be selected:
● ∇ (roughing)
● ∇∇∇ (finishing)
● Chamfering
The positions refer to the reference point:
X0 Reference point X
Y0 Reference point Y
Z0 Reference point Z
∅ Diameter of spigot
∅ 1 Diameter of blank spigot (important for determining approach position) - (only for ∇ and
∇∇∇)
Z1 Depth referred to Z0 (inc) or spigot depth (abs) - (only for ∇ and ∇∇∇)
DZ Maximum depth infeed – (only for ∇ and ∇∇∇)
UXY Finishing allowance, plane
Smaller circular spigot dimensions are obtained by calling the cycle again and program‐
ming it with a lower finishing allowance. - (only for ∇ and ∇∇∇).
UZ Depth finishing allowance (tool axis) – (only for ∇ or ∇∇∇)
FS Chamfer width for chamfering - (for chamfering only)
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only)
* Unit of feedrate as programmed before the cycle call
Hidden parameters
The following parameters are hidden. They are pre-assigned fixed values or values that can
be adjusted using setting data.
