5.1.5 Polar coordinates
If a workpiece has been dimensioned from a central point (pole) with
radius and angles, you will find it helpful to program these dimensions
as polar coordinates.
Before you program a straight line or circle in polar coordinates, you
must define the pole, i.e. the reference point, of the polar coordinate
system.
