Usually we are only used to machine metric threads, but now we also have to machine NPT threads.
How do you machine NPT inner threads with NX currently?
What are the do's and don't's?
More or less a best practice guide for machining NPT inner threads with NX, with the option to do this through FBM, which we are heavily using.
NX is designing the geometry of a simplified NPT thread with a cylindrical face, but the face is conical in reality, so that is another hurdle to get over.
Thanks in advance for any pointers for a metric thread user

If the thread is modelled with NX as Threaded hole with NPT thread, the simplified representation is a cylindrical face, but when you do a thread milling operation you will see a conical helix.
Thanks for pointing this out, we haven't tried yet how this works in NX 10, since we are currently migrating to it.
