tion
A circular spigot is machined at the programmed position (X0, Y0, Z0).
● Position pattern
Several circular spigots are machined in a position pattern
(e.g. full circle, pitch circle, grid, etc.).
The positions refer to the reference point:
X0 Reference point X – (for single position only)
Y0 Reference point Y – (for single position only)
Z0 Reference point Z – (single position only and G Code position pattern)
∅ Diameter of spigot
Z1 Spigot depth (abs) or depth relative to Z0 (inc) - (only for ∇ and ∇∇∇)
DZ Maximum depth infeed - (only for ∇ and ∇∇∇)
UXY 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 program‐
ming it with a lower finishing allowance - (only for ∇ and ∇∇∇).
UZ Depth finishing allowance (tool axis) - (only for ∇ and ∇∇∇)
∅1 Diameter of blank spigot (important for determining approach position) - (only for ∇ and
∇∇∇)
FS Chamfer width for chamfering - (for chamfering only)
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only)
