Well, i'm not in the machining industry, but i was trained to work with industry grade machinery like lathes and milling machines when i visited a tech school (comparable to College in terms of USA). In the meantime more than 30 years passed by, but i kept all the basics.
I manufactured hand made finger rings made of exotic hardwood and imo the best way to get ring blanks out of dense wood for wood turning was a CNC milling machine. It's a converted engraving machine, suitable for llimited space and equipped with powerful step motors. It would work with metals too, but the cooling using fluid would be too messy. I restricted myself to mostly automatic work, because i developed neurodermitis at the fingertips because of exposition to the fine dusts and tons of hours of wet sanding. Maybe i make 2-3 rings a year for giving away as presents. Sanding with Nitril gloves is an option, but they tend to tear and the tiniest of a wrinkle makes it hard to "feel" what is going on, and they're too sticky as well.
I've been doing this for almost 20 years. Sometimes I get lesions on my skin because of the soluble cutting oil, I've gotten used to it.

Nice job, fellow CNC machinist. That's awesome!
I did something similar here for the 10th Anniversary Art Contest in 2019. Unfortunately, the images have all since been nuked for reasons.

Here's a one I did, polished recently, in a similar vein.
Machined on a Mazak VMC 50/80, programmed on Mastercam software.
Material is 4" diameter tool steel. Engraved with .125" carbide ball endmill.

(There's other various CNC crap I've done over the years... posted and lost, somewhere in the bowels of this here famous 10 billion page thread.)
Hey Buddy! WTF?
