Check out the NX video guides I'v made
I made them for Siemens NX 7.5, but they seems to work with NX11 with some minor thing that have new/other icons, moved functions and so on.
The guides covers both turn and mill, includes threading and simulating.
There are'nt any narrations och voiceover on the videos, just quiet hard work
You can get those on the website or in an android app, your choice :)
