My opinion is that it is a slotter and the machine is set up for
making a gear. as there ar no chips around, it does not depict a
production situation, maybe a photo op of a nice looking female next to
a slotter.

and here it is, a Pratt and Whitney vertical slotter that looks very
similar to Rosie's machine.

Look at picture No. 3:

That's it, all right. Now, what was Rosie doing with the handwheels?

She's not indexing it; she isn't even looking at the indexing
handwheel. Is she eyeballing the rotary indexing and the X-Y
positioning? Unlikely, unless the bore of the gear has been marked out
on a surface plate and she's setting it up to cut to the mark.

But if she's doing that, how does she know that she's set up
perpendicular to the centerline?

Once again, it looks like a photo op.

Hi Folks,

What is this machine?
https://www.washingtonpost.com/local...=.bb8abd1abc2c

The Washington Post article from which is comes refers to it as a turret lathe (2/3 the way down the article, and just a "lathe" elsewhere) in this obituary on "Rosie the Rivetter". But it looks more like a milling machine with a rotary table than a turret lathe. Is it a gear broach?

Anybody recognize it?

I don't think it's a lathe of any kind. It looks like a
special-purpose bed-type milling machine, built to handle that big
rotary table. The drive shaft suggests that it's a production machine,
but it looks like she's locating the setup with the handwheels -- for
an operation that could have no possible relation to the powered
shaft. Here's a sharper version of that photo:

https://tinyurl.com/y9wycx3u

I question whether the photo is of a real operation, or whether it was
cooked up for the photo. The reason I say that is that there's a gear
fixtured on top, and a toolholder that looks like it could be for a
shaping operation. But the toolholder doesn't look like it's holding a
shaping tool. And there's no way, in wartime production or any kind of
production, that you would cut a gear like that with a single-point
cutting tool making straight cuts. Even if you did, one of the
handwheels would have a big and obvious index-pin dial on it.

The whole setup is screwy. The lathe chuck on top, on top of all of
that fixturing, looks like a kludge. There is no way you'd use a chuck
that way for gear work. And if the suggestion is that she's indicating
or gaging spelling intentional a gear tooth, there is no apparent
way to accomplish the measuring. And that is no freaking measuring
machine.

I'd give it four Pinocchios. d8-)
