Function
The tool drills at the programmed spindle speed and feedrate to the entered final drilling
depth. When the final drilling depth is reached, a dwell time can be programmed.
Sequence
Position reached prior to cycle start:
The drilling position is the position in the two axes of the selected plane.
The cycle creates the following sequence of motions:
● Approach of the reference plane brought forward by the safety clearance by using G0
● Traversing to final drilling depth with G1 and the feedrate programmed prior to the cycle
● Dwell time to final drilling depth
● Retraction up to the reference plane brought forward by the safety clearance using G1
● Retraction to the retraction plane with G0
