Polar Coordinates - Siemens SINUMERIK 828D Operating Manual

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.
