defined in a machine data code.
The "Pitch circle position pattern" function is used to program any
number of positions that lie on a pitch circle with a defined radius.
You can specify whether the tool should approach the next position
along a straight line or circular path (for detailed description, see
Section "Full circle position pattern").
Press the "Drilling", "Positions" and "Full/Pitch Circle" soft keys.
Positions >
Select the "Pitch Circle" position sample in the "Full/Pitch Circle"
parameter field.
