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.
