Function
The tool drills at the programmed spindle speed and
feedrate to the programmed final drilling depth.
With Boring 3, a spindle stop without orientation M5 and
then a programmed stop M0 are generated when the
final drilling depth is reached. The NC START key is
pressed to continue the retraction movement in rapid
traverse mode until the retraction plane is reached.
