6.1 Subprograms
Example for exercise: Group of four holes at three different locations
The holes are drilled with cycle G83 PECKING.
Enter the setup clearance, feed rate, etc. in the
cycle once. You can then call the cycle with
miscellaneous function M99 (see page 8-3).
Coordinates of the first hole in each group:
Group 1 X = 15 mm Y = 10 mm
Group 2 X = 45 mm Y = 60 mm
Group 3 X = 75 mm Y = 10 mm
Hole spacing: X = 20 mm
Y = 20 mm
Total hole depth: Z = 10 mm
Hole diameter: Ø = 5 mm
