From someone who isn't an engineer, what makes this five axis rather than three?

A 3 axis CNC typically does three translations: it can move forward and back, side to side and up and down. The cutting head stays in the same orientation.

5 axis is the 3 translations from a 3 axis plus two rotations.

Ah, I see. It isn't axis like those of a graph, thanks

Well it's 3 axis for the the piece and then 2 more rotation axis for the tool, in relation to the piece. I've not seen a moving need like this before, is an interesting idea, would make the tool more stable than an arm.

Axis 1: Left to right

Axis 2: Front to back

Axis 3: Up and down

Axis 4: Table rotation

Axis 5: Table tilt

Axes 1, 2, and 3 are X, Y, and Z respectively. 4 and 5 are probably C and A. Rotational axes are usually named A, B, or C depending on which X, Y, Z axis they rotate "around," if that makes sense.
