Parameters Description Unit
F2
Feedrate for thread milling mm/min
mm/tooth
Table
Thread table selection:
• without
• ISO metric
• Whitworth BSW
• Whitworth BSP
• UNC
Selection - (not
for table
"Without")
Selection, table value: e.g.
• M3; M10; etc. (ISO metric)
• W3/4"; etc. (Whitworth BSW)
• G3/4"; etc. (Whitworth BSP)
• N1" - 8 UNC; etc. (UNC)
P
- (selection
only possible for
"Table
without selection")
Pitch ...
• in MODULUS: MODULUS = Pitch/π
• in turns per inch: Used with pipe threads, for example.
When entered per inch, enter the integer number in front of the decimal point in the
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.

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.
