Circular pattern
Full circle
•
The circumferential slots are positioned around a full circle. The distance from one
circumferential slot to the next circumferential slot is always the same and is
calculated by the control.
Pitch circle
•
The circumferential slots are positioned around a pitch circle. The distance from
one circumferential slot to the next circumferential slot can be defined using angle
α2.
The positions refer to the reference point:
X0 Reference point X – (only for single position)
Y0 Reference point Y – (only for single position)
Z0 Reference point Z – (only for single position)
(only for G code)
Face C: The positions refer to the reference point:
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)
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)
