Area of exclusion
Surface A is to be machined without the portion overlapped by B:
n
The surfaces A and B must be programmed in separate programs
without radius compensation.
n
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.)
n The surfaces A and B must be programmed in separate programs
without radius compensation.
n In the contour formula, the surfaces A and B are processed with the
"intersection with" function.
