Function
The tool drills at the programmed spindle speed and feedrate to the entered final drilling depth.
During drilling 3, a spindle stop without orientation M5 is generated after reaching the final drilling depth, followed by a
programmed stop M0. Pressing the following key continues the retraction movement at rapid traverse until the retraction
plane is reached:
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 call
● Spindle stop with M5
● Press the following key:
● Retraction to the retraction plane with G0
