● 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
● Climb milling: Mill thread in one cycle.
● Up-cut operation milling: Mill thread in one cycle.
● Synchronous operation - Up-cut operation: Mill thread in two cycles: rough cutting is
performed by Up-cut operation milling with defined allowances, then finish cutting is
performed by climb milling with milling feedrate FS.

10.1.10 Positioning and position patterns
Function
The positions are programmed after the technology (cycle call). Several position patterns are
available:
● Arbitrary positions
● Position on a row, on a grid or a frame
● Position on a full or pitch circle
Several position patterns can be programmed in succession. They are executed in the order
in which you program them.
Note
The number of positions that can be programmed in the one "Positions" step is limited to a
maximum of 600!
