Parameter  Description  Unit 
Infeed (only for ∇ and ∇ 
+ ∇∇∇) 
 
•  Linear: 
Infeed with constant cutting depth 
•  Degressive: 
Infeed with constant cutting cross-section 
 
Thread 
 
•  Internal thread 
•  External thread 
 
X0  Reference point X from thread table ∅ (abs)  mm 
Z0  Reference point Z (abs)  mm 
Z1    End point of the thread (abs) or thread length (inc)  
Incremental dimensions: The sign is also evaluated. 
mm 
Amount of crown 
 
Allowance to compensate for sag ( - only for external thread and G= 0) 
•  XS 
Segment height, crowned thread 
•  RS 
Radius crowned thread 
Positive values: Convex 
Negative values: Concave

Thread advance (inc) 
The starting point for the thread is the reference point (X0, Z0) brought forward by 
the thread advance W. The thread advance can be used if you wish to begin the 
individual cuts slightly earlier in order to also produce a precise start of thread. 
Thread run-in (inc) 
The thread run-in can be used if you cannot approach the thread from the side and 
instead have to insert the tool into the material (e.g. lubrication groove on a shaft).  
Thread run-in = thread run-out (inc)

LR  Thread run-out (inc) 
The thread run-out can be used if you wish to retract the tool obliquely at the end 
of the thread (e.g. lubrication groove on a shaft). 
mm 
H1  Thread depth from thread table (inc)  mm 
Infeed slope as flank (inc) – (alternative to infeed slope as angle) 
DP > 0: Infeed along the rear flank  
DP < 0: Infeed along the front flank 
mm 
DP 
 
or 
αP 
Infeed slope as angle – (alternative to infeed slope as flank) 
α > 0: Infeed along the rear flank 
α < 0: Infeed along the front flank 
α = 0: Infeed at right angle to cutting direction 
If you wish to infeed along the flanks, the maximum absolute value of this 
parameter may be half the flank angle of the tool.
