Operation Manual

306 Teach-in mode
4.7 Drilling cycles
Cycle run
1 Position spindle to spindle angle C (in Manual mode, machining
starts from the current spindle angle)
2 If defined, move at rapid traverse to hole starting point Z1
3 First pass (pecking depth: P)—drill with reduced feed rate, if
defined
4 Retract by retraction length B—or to the hole starting point
and advance again to last pecking depth minus safety clearance
5 Next pass (pecking depth: "last depth – IB" or JB)
6 Repeat 4 to 5 until hole end point Z2 is reached
7 Last drilling pass—depending on through drilling variants V:
 Through-drilling reduction:
– Drill at programmed feed rate to position Z2 – AB
– Drill at reduced feed rate to hole end point Z2
 No through drilling reduction:
– Drill at programmed feed rate to hole end point Z2
– Remain at end of hole for dwell time E, if defined
8 Retract
 If Z1 is programmed, to hole starting point Z1
 If Z1 is not programmed, to starting point Z
9 Move to the tool change point according to the G14 setting
