There are no “typical values” when you’re running a mill or lathe. You could look up “speeds and feeds”, but that’s really just a table that you plug into an equation to figure out how to set the machine. It all depends on what you’re doing and what you’re doing it with. Drilling a hole with a high speed steel drill bit is going to be a bit different than drilling it with a carbide spade, and all that is going to depend heavily on whether you’re trying to run through titanium or tin. You need to fine tune running “x” bit through “y” material for a “z” sized cut.
Essentially, this is the knowledge that separates skilled labor from manual labor, and machining is (was, RIP cnc button pushers) skilled labor.
At the end of the day for most metal machining you’ll need between 50hp and 100hp to be up to modern standards. If you want to get that through steam or electric motors or whatever that’s up to you
You’d be surprised how slow machining can be. Cutting speeds are all in sfm (surface feet per minute) and when you have a BIG part, them feets add up quick. Check out videos of big old vertical lathes running big parts. You can get down to a quarter of an rpm but the flange or fitting is so fucking huge that you’re still pushing 100-200 sfm at the bit.
