Example for exercise: Three groups of four holes (see page 6-4) with three different tools
Machining sequence:
Countersinking – Drilling – Tapping
Machining data is entered in cycle G83: PECK
DRILLING (see page 8-4) and cycle G84:
TAPPING (see page 8-6). The tool moves to the
hole groups in a subprogram, while the machin-
ing 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
Hole spacing:
IX = 20 mm
IY = 20 mm
Hole data:
Countersinking
ZC =
3 mm
Ø = 7 mm
Drilling
ZD = 15 mm
Ø = 5 mm
Tapping
ZT = 10 mm
Ø = 6 mm
