Self centering on threads question

[[Lu...]]

Hello, I have a quick question. I am trying to use self centering for a helix path on threads, but i have a difficult time understanding the graphic. Could someone explain what it is? Is it a top down view or a front view with the threads cut in half? What about that flat on the bottom what does that mean? I have tried to find information in the help menu and on this forum but i cant seem to find an explination anywhere. would this be the appropriate settings for internal left handed threads? Any help is appreciated thank you

I have found no difference between green arrow up and down - i would say it's initial force push. If you are not really close to bottom of a hole, then you are good.

In other words - you are good to go

Thank you, what about the blue arrows? would that be different depending on if it was internal/external? Would it depend on if the threads were facing up and down or if it was horizontal?

I think this is suitable even for external thread.

There is option for bottom/upper, side and corner

How do you control helix movement to make sure probing is not off-center falling in and out of thread pitch?

I'm curious, never thought of doing this.

Most of the work will handle active head and defined pitch. Combination of probing force, slow speed and filtering will do the job
