Parameter Description Unit
Infeed along the flank
Infeed with alternating flanks (alternative)
Instead of infeed along one flank, you can infeed along alternating flanks to avoid
always loading the same tool cutting edge. As a consequence you can increase
the tool life.
α > 0: Start at the rear flank
α < 0: Start at the front flank
D1 or ND
(only for ∇ and
∇ + ∇∇∇)
First infeed depth or number of roughing cuts
The respective value is displayed when you switch between the number of
roughing cuts and the first infeed.
mm
U Finishing allowance in X and Z – (only for ∇ and ∇ + ∇∇∇) mm
NN Number of noncuts - (only for ∇∇∇ and ∇ + ∇∇∇)
VR Return distance (inc) mm
No
α0 Starting angle offset Degrees
Yes
N Number of thread turns
The thread turns are distributed evenly across the periphery of the
turned part; the 1st thread turn is always located at 0°.
DA Thread changeover depth (inc)
First machine all thread turns sequentially to thread changeover
depth DA, then machine all thread turns sequentially to depth 2 ·
DA, etc. until the final depth is reached.
DA = 0: Thread changeover depth is not taken into account, i.e.
finish machining each thread before starting the next thread.
mm
Multiple threads
Machining:
• Complete, or
• from turn N1
N1 (1...4) start thread N1 = 1...N
or
• only thread NX
NX (1...4) 1 from N threads
