Area of inclusion
Both areas A and B are to be machined, including the overlapping
area:
The areas A and B must be entered in separate programs
without radius compensation.
In the contour formula, the areas A and B are processed with
the "joined with" function.

Area of exclusion
Area A is to be machined without the portion overlapped by B:
The areas A and B must be entered in separate programs
without radius compensation.
In the contour formula, the area B is subtracted from the area A
with the
without function.
