Travel commands with polar coordinates

9.3.1

Reference point of the polar coordinates (G110, G111, G112)

Function
The point from which the dimensioning starts is called the pole.
The pole can be specified in Cartesian or polar coordinates.
The reference point for the pole coordinates is clearly defined with the
commands. Absolute or incremental dimension inputs therefore have no effect.

Note:
The commands
: Specification of the pole in Cartesian coordinates
: Specification of the pole in polar coordinates
: Polar angle
AP=...
Angle between the polar radius and the horizontal axis of the
working plane (e.g. X axis for
rotation runs counterclockwise.
Range of values: ± 0...360°

The specification is always in absolute positive values in [mm]
or [inch].
