only possible for
in turns per inch: Used with pipe threads, for example.

table selection
When entered per inch, enter the integer number in front of the decimal point in the
"without")
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.
αS Starting angle offset - (only for tapping without compensating chuck)
(only for G code)
S Spindle speed - (only for tapping without compensating chuck)
(only for G code)
Machining The following machining technologies can be selected:
(without
1 cut

compensating
The thread is drilled in one cut without interruption.
chuck)
Chipbreaking

The drill is retracted by the retraction amount V2 for chipbreaking.
Stock removal

The drill is retracted from the workpiece for stock removal.
D Maximum depth infeed - (only when used without compensating chuck, stock removal
or chipbreaking)
Retraction Retraction distance - (only without compensating chuck, chipbreaking)
Manual

Retraction distance after each machining step (V2)
Automatic

Without retraction distance after each machining step
V2 Retraction distance after each machining step – (only without compensating chuck,
chipbreaking and manual retraction)
Distance by which the drill is retracted for chipbreaking.
V2 = automatic: The tool is retracted by one revolution.
DT Dwell time at final drilling depth in seconds
(only for G code)
SR Spindle speed for retraction - (only for when a compensating chuck is not used)
(only for G code)
SDE Direction of rotation after end of cycle:
(only for G code)
