6.4 Nesting
Example for exercise: Group of four holes at three positions (see page 6-4), but with three different tools
Machining sequence:
Countersinking - Pecking - Tapping
The drilling operation is programmed with cycle
G83: PECKING (see page 8-4) and cycle G84:
TAPPING (see page 8-6). The groups of holes
are approached in one subprogram, and the
machining is performed in a second subprogram.
Coordinates of the first hole in each group:
1 X = 15 mm Y = 10 mm
2 X = 45 mm Y = 60 mm
3 X = 75 mm Y = 10 mm
Spacing between
holes
IX = 20 mm IY = 20 mm
Hole data:
Countersinking
ZC = 3 mm Ø = 7 mm
Pecking ZP = 15 mm Ø = 5 mm
Tapping ZT = 10 mm Ø = 6 mm
