I'm pretty sure almost everything we post out here for 2 through 5 axis is in G54. I'm speculating though, because I haven't yet programmed for each of every one of our machines. We use third party tool managment, verification and post processing. I have to add multiple comments for each toolpath and a manual toolchange line for every tool too.
I have had three days of basic training, but because of the way we do things here some of it really doesn't apply to how I have to do things so that's why I'm trying to figure out the best approach. I have a pretty strong CAM background and really don't have too hard of a time figuring out the toolpaths in NX it's all of the ancillary stuff that's going on that I can't get a decent answer on from any co-workers. This thread is the best information I've received so far.
