Area of inclusion
Both areas (element A and element B) are to be
machined - including the area of overlap.
l
A and B must be pockets.
l
The first pocket (in Cycle 14) must start outside
the second.

Area of exclusion
Surface A is to be machined without the portion
overlapped by B:
l
A must be a pocket and B an island.
l
A must start outside of B.

Area of intersection
Only the area of intersection of A and B is to be
machined. (All of surfaces A and B are to be left
unmachined except the portion overlapped by
both.)
l
A and B must be pockets.
l
A must start inside B.
