Machining
Single position

position
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 – (only for single position 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
programming 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)
