Description
Select the thread pitch / turns for table "without" or specify the thread pitch/turns
corresponding to the selection in the thread table:
Thread pitch in mm/revolution
•
Thread pitch in inch/revolution
•
Thread turns per inch
•
Thread pitch in MODULUS
•
∇ (roughing)
•
∇∇∇ (finishing)
•
∇ + ∇∇∇ (roughing and finishing)
•
Linear:
•
Infeed with constant cutting depth
Degressive:
•
Infeed with constant cutting cross-section
Internal thread
•
External thread
•
Reference point X ∅ (abs, always diameter)
Reference point Z (abs)
End point X ∅ (abs) or end point in relation to X0 (inc) or thread taper
incremental dimensions: The sign is also evaluated.
End point Z (abs) or end point in relation to Z0 (inc)
Incremental dimensions: The sign is also evaluated.
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)
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).
Thread depth (inc)
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
