Example for exercise: Group of four holes at three positions (see page 6-4), but with three different tools
Machining sequence:
Countersinking – Drilling – Tapping
The drilling operation is programmed with cycle
1: PECK DRILLING (see page 8-5) and cycle 2:
TAPPING (see page 8-7). 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
ZS = 3 mm Ø = 7 mm
Drilling ZT = 15 mm Ø = 5 mm
Tapping ZG = 10 mm Ø = 6 mm
