feed rate etc. once in the cycle. 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:
Z = 10 mm
Hole diameter:
Ø = 5 mm
