Machining
• ∇ (roughing)
• ∇∇∇ (finishing)
• ∇ + ∇∇∇ (roughing and finishing)
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
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
Note:
the pitch change per revolution "G" must be "0".

LW
or
LW2
or
LW2 = LR
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)
mm
mm
mm
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
Thread depth from thread table (inc)
DP
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
