I have a stupid question.

I don't understand the power requirements for machines.

I.e., the Minimill power calls for 195-250 VAC/50 A,
366-425 VAC/20 A. Does that mean it can take one OR three phase?

Even the VF-4 says 195-260 VAC/50 A, 354-488 VAC/30 A.

What am I missing?

If my power box at home says Mains 100 Amp Max, 120/240 VAC, then I could run a VF-4 in my bedroom?
 
Your going to need 3 phase.
A phase converter rated for your amp draw will do the trick.
If your home entrance is only 100 amps you might have an issue running rotary converter.

On a smaller mill a Phase perfect DPC 10 should do and should work for a smaller machine.

Don't forget your going to need to power a decent size air compressor.

Lot's of discussion on this in the Phase converter section.

He can run an RPC on 100A service, I run my 15hp Phasemaster on 100A service. The total amount of motor horsepower is critical, and you're right, he does need to allow capacity for a compressor and other shop loads, as well as some for the house. I have had a total of ten horsepower running simultaneously without incident on 100A service, off a 60A breaker. The OP is well advised to oversize the RPC by at least a factor of 2.

To the OP, look in your manual, it seems as though a Haas mini can run on 240v 1ph. Also, the current requirements will fit your service.
