10.7.16 Circle polar
If you want to program a circle or arc using polar coordinates, you can use the "Circle Polar"
function.
A circle in the polar coordinate system is defined by the angle α. Depending on the selected
machining plane, the angle refers to another axis. The direction in which a positive angle points
also depends on the machining plane.
Machining plane Rotate Face Peripheral
Reference axis for angle Z X Y
Positive angle in direction of the axis X Y Z
The tool traverses a circular path from its actual position to the programmed end point (angle)
at the machining feedrate. The radius is obtained from the distance between the actual tool
position and the defined pole, i.e. the circle start and end point positions are at the same
distance from the pole.
The 1st arc in polar coordinates entered after the pole must be programmed in absolute
dimensions. You can program any additional lines or arcs also in incremental dimensions.
