This article answers all my questions. I hope it's accurate https://www.lavelocita.cc/guides-page/facing-carbon-fibre-bike-frames

That article is an incredibly long way of saying carbon is more abrasive than steel or aluminium. There’s no black art to it. Cutters won’t last as long, but you basically use the same cutters.
Edit: in the factory, they’ll be jigged up to not have to do it by hand. They’ll just clamp the frame in a jig on the machine and hit it with the cutter while flooding it with coolant. 99% of the time it’ll be accurate enough.

I have no experience of CF manufacturing except a tiny bit of tube to tube using an alloy BB shell so I don't know. I'd have thought external part dims on parts in moulds should come out pretty accurate from the mould but I'm not sure.
