12. COMPENSATION FUNCTION
(2) In addition to the condition (1), the angle between the start point and
end point on the beam 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).
Beam center path
N5 G01 G91 X800.0 Y200.0 D1 ;
N6 G02 X320.0 Y–160.0 I–200.0 J–800.0 D2 ;
N7 G01 X200.0 Y–500.0 ;
(Cutter compensation value corresponding to D1 : r
(Cutter compensation value corresponding to D2 : r
In the above example, the arc in block N6 is placed in the one quadrant.
But after cutter compensation, the arc is placed in the four quadrants.
