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 as polar coordinates.
You can program straight lines and circles as polar coordinates.
Defining a pole
You must define the pole before you can program a straight line or circle in polar
coordinates. This pole acts as the reference point of the polar coordinate system.
The angle for the first line or circle then needs to be programmed in absolute coordinates.
You can program the angles for any additional straight lines and circles as either absolute or
incremental coordinates.
