Area of exclusion

Surface A is to be machined without the portion overlapped by B:

„

The surfaces A and B must be entered in separate programs without
radius compensation.

„

In the contour formula, the surface B is subtracted from the surface
A with the “joined with complement of” function.

Contour definition program:

Area of intersection

Only the area where A and B overlap is to be machined. (The areas
covered by A or B alone are to be left unmachined.)

„

The surfaces A and B must be entered in separate programs without
radius compensation.

„

In the contour formula, the surfaces A and B are processed with the
“intersected with” function.
