Parameter Description
Face Y: The positions refer to the reference point:
CP Positioning angle for machining area – (only single position)
X0 or L0 Reference point X or reference point length polar – (only for single position)
Y0 or C0 Reference point Y or reference point angle polar – (only for single position)
Z0 Reference point Z – (only for single position)
(only for
ShopTurn)
Peripheral surface C: The positions refer to the reference point:
Y0 or C0 Reference point Y or reference point angle polar – (only for single position)
Z0 Reference point Z – (only for single position)
X0 Cylinder diameter ∅ – (only for single position)
(only for
ShopTurn)
Peripheral surface Y: The positions refer to the reference point:
C0 Positioning angle for machining surface – (only for single position)
Y0 Reference point Y – (only for single position)
Z0 Reference point Z – (only for single position)
X0 Reference point X – (only for single position)
(only for
ShopTurn)
∅ Diameter of spigot
Z1 or X1 Spigot depth (abs) or depth relative to Z0 or X0 (inc) - (only for ∇ and ∇∇∇)
(Z1 for machining surface, face C/Y or X1 for peripheral surface C/Y)
DZ or DX Maximum depth infeed - (only for ∇ and ∇∇∇)
(DZ for machining surface, face C/Y or DX for peripheral surface C/Y)
UXY or UYZ Plane finishing allowance for the length (L) and width (W) of the circular spigot.
Smaller circular spigot dimensions are obtained by calling the cycle again and
programming it with a lower finishing allowance. - (only for ∇ and ∇∇∇)
(UXY for machining surface, face C/Y or UYZ for peripheral surface C/Y)
UZ or UX Depth finishing allowance (tool axis) - (only for ∇ and ∇∇∇)
(UZ for machining surface, face C/Y or UX for peripheral surface C/Y)
∅1 Diameter of blank spigot (important for determining approach position) - (only for ∇ and
∇∇∇)
FS Chamfer width for chamfering - (for chamfering only)
ZFS or XFS Insertion depth of tool tip (abs or inc) - (for chamfering only)
(ZFS for machining surface, face C/Y or XFS for peripheral surface C/Y)
