Function
The tool drills at the programmed spindle speed and feedrate to the entered final drilling
depth. During boring pass 4, a dwell time, a spindle stop without orientation M5 and a
programmed stop M0 are generated when the final drilling depth is reached. Pressing
<CYCLE START> traverses the outward 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
● Dwell time at final drilling depth
● Spindle and program stop with M5 M0. After program stop, press the <CYCLE START>
● Retraction to the retraction plane with G0
