The new end position is defined relative to a pole, see defining the pole G110, G111, G112
Parameters
G0 Rapid traverse movement
G1 Linear interpolation
G2 Circular interpolation clockwise
G3 Circular interpolation counter-clockwise
AP= Polar angle, value range ±0…360°, the polar angle can be
defined both absolutely and incrementally.
RP= Polar radius in mm or inches always in absolute positive
values.
=AC(...) Absolute dimensioning
=IC(...) Incremental dimensioning
