Description
Number of teeth per cutting edge
Single or multiple toothed milling inserts can be used. The motions required are
executed by the cycle internally, so that the tip of the bottom tooth on the milling
insert corresponds to the programmed end position when the thread end position
is reached. Depending on the cutting edge geometry of the milling insert, the
retraction path must be taken into account at the base of the workpiece.
Machining position:
Single position

The positions refer to the center point:
Reference point X – (for single position only)
Reference point Y – (for single position only)
Reference point Z
End point of the thread (abs) or thread length (inc)
Nominal diameter
Example: Nominal diameter of M12 = 12 mm

Pitch
If the cutter has several teeth, the thread pitch is determined by the tool.
For a thread pitch entered in turns/'', enter the integer 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 fields.
