Function
The tool drills at the programmed spindle speed and feedrate to the entered final thread depth.
This cycle is used to program tapping with the compensating chuck:
● Without encoder
● With encoder.
Sequence
Tapping with compensating chuck without encoder
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
● Tapping to the final drilling depth
● Dwell time at tapping depth (parameter DTB)
● Retraction to the reference plane brought forward by the safety clearance
● Retraction to the retraction plane with G0
Sequence of operations
Tapping with compensating chuck with encoder
Position reached prior to cycle start:
The drilling position is the position in the two axes of the selected plane.
