Function
The tool drills at the programmed spindle speed and feedrate to the entered final drilling depth. When drilling with stop, a
spindle stop without orientation M5 and a programmed stop M0 are generated when the final drilling depth is reached.
Pressing the following key 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 call
● Dwell time at final drilling depth
● Spindle and program stop with M5 M0. After program stop, press the following key:
● Retraction to the retraction plane with G0
150
