Parameter
Description
Unit
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.

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
