6.1 Subprograms
Example for exercise: Group of four holes at three different locations
The hales are drilfed with cycle 1 PECKING,
You, enter the Wal hole depth, setup clearance,
drilling feed rate etc. once in the cycle.
Yau can then call the cycle w&h the
miscellaneous function M99 (see page E&6)+
Coordinates of the first hole in each group:
Group @ X = 15mm Y = IOmm
Group @
X =45mm Y =60mm
Group @
X =75mm Y = IOmm
Spacing of holes:
IX = 20 mm IY = 20 mm
Total hole depth (DEPTH): Z = IOmm
Hole diameter: 0 = 5mm
