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.

Climbing - conventional: Mill thread in two cycles: rough cutting is performed by
•
conventional milling with defined allowances, then finish cutting is performed by
climb milling with milling feedrate FS.
FS Finishing feedrate - (only for climbing - conventional milling)

Positioning and position patterns

Function
After you have programmed the technology (cycle call), you must program the positions.
Several position patterns are available:
● Arbitrary positions
● Position on a line, on a grid or frame
● Position on a full or pitch circle
Several position patterns can be programmed in succession. They are traversed 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 400!
