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

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.

Of course it's a photo op(portunity), there aren't any chips and she
isn't wearing safety glasses. Her hands are on two handles to support
herself leaning forward. Why would you expect 'cinema verite' in a
busy factory?

The P&W slotter may have been the only machine available that allowed
the bulky tripod-mounted view camera to catch the operator's face
while they pretend to work. I've done enough industrial photography to
know how difficult that can be.

I suspect there were many bracketing shots to obtain a proper exposure
of her skin without excessive glare off the bare metal. There is
contrast and texture fairly deep into the shadows without much
overexposure of the highlights.
