Straight line polar

When you want to program a straight line in polar coordinates, you can use the "Straight Polar"
function.
A straight line in the polar coordinate system is defined by the length L and 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
Reference axis for angle
Positive angle in direction of the axis
The tool traverses a straight line from its current position to the programmed end point at the
machining feedrate or at rapid traverse.
The 1st line 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.
