Parameter Description Unit
Multiple threads 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.
