Overlapping contours
Pockets and islands can be overlapped to form a new contour. You
can thus enlarge the area of a pocket by another pocket or reduce it
by an island.
Subprograms: Overlapping pockets
The subsequent programming examples are contour
subprograms that are called by Cycle 14 CONTOUR
GEOMETRY in a main program.
Pockets
A
and
B
overlap.
The TNC calculates the points of intersection S
1
and S
2
(they do not
have to be programmed).
The pockets are programmed as full circles.
Subprogram 1: Left pocket
Subprogram 2: Right pocket
Area of inclusion
Both surfaces
A
and
B
are to be machined, including the mutually
overlapped area:
■ The surfaces
A
and
B
must be pockets.
■ The first pocket (in Cycle 14) must start outside the second
pocket.
