all the way around the thread mill

[prefetch]

how do i get fusion 360 to do a complete revolution when it's doing a external threadmill operation?

when i run this, it doesn't actually make it completely all the way around - there's 1 degree of "non-thread" left over.

i thought my tool diameter was off, but it's not - i really just want to try and force fusion to cut further around, but it appears as though there are no options to do this.

how is this supposed to work??

What are you using for cycles and is that a standard thread you are cutting? I ask because I've seen some issues where people cut non-standard threads (water bottle) and have to resort to Trace or the like to accomplish what they need.

For a standard thread milling operations, it all comes down to heights. If you have the bottom height set to exactly one pitch below the top height, yes, you will get that result. However, it's really not good practice to do that; usually it's a one and a quarter to one and a half turns for full form thread mills. Internal or External have same results

Edit: Setting Lead In/Out Radius to zero does make them go slightly past 360 degrees of revolution. If you are forced for some reason to not use the solution I listed above, you have this option. However, I'm not sure how the tool will like plunging straight into the cut.....

i'm using a standard 12 tpi UNC thread.

(i'm using this kind of a thread mill tool)

ah - okay.  i see what you mean now.  i only need it to go around once because i have a full threaded tool, but now i see that if i adjust the height, i can trick it into an overlap:

i'll try this out in the mill and see how it goes.  thanks - i just wasn't thinking in the frame of mind where the height changed the horizontal path!
