Poles 1 to 3 are defined as follows:
● Pole 1 with G111 X… Y…
● Pole 2 with G110 X… Y…
● Pole 3 with G112 X… Y…
2.9.3.2 Travel commands with polar coordinates (G0, G1, G2, G3, AP, RP)
Travel commands with polar coordinates are useful when the dimensions of a workpiece or part
of the workpiece are measured from a central point and the dimensions are specified in angles
and radii (e.g. for drilling patterns).
