Tapping (CYCLE84, 840)
Function
You can machine an internal thread with the "tapping" cycle.
The tool moves to the safety clearance with the active speed and rapid traverse. The spindle
stops, spindle and feedrate are synchronized. The tool is then inserted in the workpiece with
the programmed speed (dependent on %S).
You can choose between drilling in one cut, chipbreaking or retraction from the workpiece for
swarf removal.
Depending on the selection in the "Compensating chuck mode" field, alternatively the
following cycle calls are generated:
● With compensating chuck: CYCLE840
● Without compensating chuck: CYCLE84
When tapping with compensating chuck, the thread is produced in one cut. CYCLE84
enables tapping to be performed in several cuts if the spindle is equipped with a measuring
system.
