Function
The tool drills at the programmed spindle speed and
feedrate to the programmed final drilling depth. A
dwell time can be allowed to elapse when the final
drilling depth has been reached.
Sequence of operations
Position reached prior to cycle start:
The drilling position is the position in the two axes of
the selected plane.
The cycle implements the following motion
sequence:
• Approach of the reference plane brought forward
by the safety distance with G0
• Traverse to final drilling depth with the feedrate
(G1) programmed in the calling program
• Dwell time at final drilling depth
• Retraction to retraction plane with G0.
