When is it considered a firearm?
When the barrel is pressed into the front trunnion?
Thanks

It's all about the receiver.

There is no hard fast rule to my knowledge.
Every one that produces a '80%' must submit it for approval before it can be sold. I believe it's on a case by case basis.
That being said........From the 80% receivers that have been submitted, and approved for sale as 'Not a Firearm' by the ATF we can say basically two types that I have seen:
Holes but not bent in the 'U' shape (flat)
Bent into 'U' shape but no fire control group holes.

Barrel, and trunnions have nothing to do with it.
NDS 100% receivers don't have trunnions or barrels attached but are sold (and DROsed) as a firearm.

It seems to be once the receiver is bent and has fire control holes that they consider it a firearm.
Anything beyond that is work being done TO a firearm, not a firearm being manufactured.
