15. COMPENSATION FUNCTION
(2) In addition to the condition (1), the angle between the start point and
end point on the Tool nose radius center path is quite different from
that between the start point and end point on the programmed path
in circular machining(more than 180 degrees).

In the above example, the arc in block N6 is placed in the one quadrant.
But after tool nose radius compensation, the arc is placed in the four
