12. COMPENSATION FUNCTION
Normally there is almost no possibility of generating this situation.
However, when G41 and G42 are changed, or when a G40 was
commanded with address I, J, and K this situation can occur.
In this case of the figure, the cutter compensation is not performed with
more than one circle circumference: an arc is formed from P
shown. Depending on the circumstances, an alarm may be displayed due
to the ”Interference Check” described later. To execute a circle with more
than one circumference, the circle must be specified in segments.
