4.2.2 Traversing commands with polar coordinates, (G0, G1, G2, G3 AP=..., RP=...)
Function
The polar coordinate method is useful only if a workpiece or part of a workpiece has radius
and angle measurements. Polar coordinates can be used to program these dimensions
directly in accordance with the drawing.
If the dimensions of a workpiece, such as those in hole patterns, proceed from a central
point, then the dimensions are given in terms of angles and radii.
