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
Climbing: Mill thread in one cycle.

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)

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.
