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 – (single position only and G Code position pattern)
∅ Diameter of spigot
Z1 Spigot depth (abs) or depth relative to Z0 (inc) - (only for ∇ and ∇∇∇)
