SL cycles with simple contour formula

Fundamentals

SL cycles and the simple contour formula enable you to form
contours by combining up to 9 subcontours (pockets or islands) in
a simple manner. You define the individual subcontours (geometry
data) as separate programs. In this way, any subcontour can be
used any number of times. The TNC calculates the contour from the
selected subcontours.
The memory capacity for programming an SL cycle (all
contour description programs) is limited to
The number of possible contour elements depends on the
type of contour (inside or outside contour) and the number
of contour descriptions. You can program up to
elements.
