Parameters
P Pitch ...
in MODULUS: MODULUS = Pitch/π
- (selection 
only possible for
in mm/rev

table selection
in inch/rev

"without")
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.
The pitch is determined by the tool used.
S / V Spindle speed or
constant cutting rate
SR Spindle speed for retraction
VR Constant cutting rate for retraction
1. Cut
Machining 
The thread is drilled in one cut without interruption.
Chipbreaking

The drill is retracted by the retraction distance V2 for chipbreaking.
Stock removal

The drill is retracted from the workpiece for stock removal.
Z0 Reference point Z)
Z1 End point of the thread (abs) or thread length (inc)
D Maximum depth infeed - (for stock removal or chipbreaking only)
Retraction - (only for "chipbreaking" operation)
Retraction distance
Manual

Automatic

V2 Retraction distance (only for "manual" retraction)
Distance through which the tap is retracted for chipbreaking.
V2 = automatic: The tool is retracted by one revolution.

Transformations

To make programming easier, you can transform the coordinate system. Use this possibility,
for example, to rotate the coordinate system.
Coordinate transformations only apply in the actual program.
You can define the following transformations:
● Offset
● Rotation
● Scaling
● Mirroring
● Rotation C axis
