Machining
position

Single position
A circular pocket is machined at the programmed position (X0, Y0, Z0).

Position pattern
Several circular pockets are machined in a position pattern
(e.g. full circle, pitch circle, grid, etc.).
X0
Y0
Z0 The reference points refer to the center point of the circular pocket:
Reference point X – (for single position only)
Reference point Y – (for single position only)
Reference point Z – (for single position only)
