Function
The tool drills at the programmed spindle speed and feedrate to the entered final drilling
depth.
During boring 3, a spindle stop without orientation M5 is generated after reaching the final
drilling depth, followed by a programmed stop M0. Pressing <CYCLE START> 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
● Spindle stop with M5
● Press <CYCLE START>
● Retraction to the retraction plane with G0
