3.6.5 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 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 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 further
lines and circles as either absolute or incremental coordinates.
