Parameter Description
Machining type
Plane by plane

Solid machine circular pocket plane-by-plane
Helical

Solid machine circular pocket helically
Machining
Single position

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.).
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 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)
(only for
ShopTurn)
Peripheral surface Y: The positions refer to the reference point:
C0 Positioning angle for machining surface – (only for single position)
Y0 Reference point Y – (only for single position)
Z0 Reference point Z – (only for single position)
X0 Reference point X – (only for single position)
(only for
ShopTurn)
