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 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 "intersection with" function.

Contour definition program:

52 DECLARE CONTOUR QC1 = "POCKET_A.H"

53 DECLARE CONTOUR QC2 = "POCKET_B.H"

54 QC10 = QC1 & QC2

Contour machining with SL Cycles

The complete contour is machined with the SL Cycles

20 to 24 (See "Overview", page 218).
