first parameter field and the figures after the decimal point as a fraction in the second
and third field.
● in mm/rev
● in inch/rev
The pitch is determined by the tool used.
Z2 Retraction amount before thread milling
The thread depth in the direction of the tool axis is defined using Z2. Z2 is relative to the
tool tip.
∅ Nominal diameter
Milling direction
● Climbing: Mill thread in one cycle.
● Conventional: Mill thread in one cycle.
● Climbing - conventional: Mill thread in two cycles: rough cutting is performed by
conventional milling with defined allowances, then finish cutting is performed with
climb milling with milling feedrate FS.
FS Finishing feedrate rate - (only for climbing - conventional milling)
