The processing proceeds like this for a linear move in my program:

- feedrate is in SQRT(sum of squares) fashion for any number of
linear axes, and the angular ones go along for the ride
- feedrate is in deg/sec for a lone angular axis
- feedrate is in deg/sec for the first of several angular axes, the
rest go along for the ride.

- If any axis is commanded to go too fast (as with the above), each
axis is slowed down accordingly to make the move as fast as possible
overall.

- The overall acceleration is then set to fit the constraints of the
most slowly accelerating axis to keep it all linear.

Not that this is enormously helpful, but that's how I made this sort
of N-axis feed problem tractable if anyone cares to critique it.

To make it even more general, the SQRT(sum of squares) should be
split into two parts to figure the feedrate for the XY-UV hotwire
foam cutting folks. It's confusing otherwise, and I don't think
anybody is cutting a 4th-dimensional part in our neck of the universe!
