Polar angle AP=...
The angle is always referred to the horizontal axis (abscissa) of the plane (for example, with
G17: X axis). Positive or negative angle specifications are possible.
The polar angle remains stored and must only be written in blocks in which it changes, after
changing the pole or when switching the plane.

Pole definition, programming
G110 Pole specification relative to the setpoint position last programmed (in the
plane, e.g. with G17: X/Y)
G111 ; Pole specification relative to the origin of the current workpiece coordinate
system (in the plane, e.g. with G17: X/Y)
G112 ; Pole specification, relative to the last valid pole; preserve plane
Note
Pole specifications
• Pole definitions can also be performed using polar coordinates. This makes sense if a
pole already exists.
•
If no pole is defined, the origin of the current workpiece coordinate system will act as the
pole.
