You can then call the cycle with the
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
Spacing of holes:
IX = 20 mm IY = 20 mm
Total hole depth (DEPTH): Z = 10 mm
Hole diameter: Ø = 5 mm
