Determine point of intersection between two contour elements (INTERSEC)

INTERSEC determines the point of intersection of two normalized contour elements from the
contour tables generated using CONTPRON.
Syntax
<Status>=INTERSEC(<contour table_1>[<contour element_1>],
<contour table_2>[<contour element_2>],<intersection
point>,<machining type>)
Meaning
INTERSEC:
<Status>:
<contour table_1>:
<contour element_1>:
<contour table_2>:
<contour element_2>:
<point of intersection>:
<machining type>:
