I have a swivel milling vise. Do I understand it right, as it seems,
that CNC does not care for swiveling and I would be best served taking
the swivel base off?

Usually people go for a rotary table. Then you can "swivel" your work piece
in a controlled repeatable manner. Put a motor on your rotary table and,
"BAM!" 4 axis machining. I can usually clamp most work pieces without one
to get what I want, but it would be nice for a little more consistent tooth
position for cutting some types of gears. If I had a bigger working
envelope I would be really tempted to go 5 axis and put a trunnion table or
a chuck and spindle on top of a rotary table. There are some pockets that
are just a pain to program using just 3 axis.
