Good morning.

Taking it from the beginning you need CAD, then CAM, then a controller for a CNC machine.
Cad you know about, CAM is a program like Cut3D which turns the drawing into G code which is just a text file containing way points, go to xx go to yy etc.
The controller in 95% of home shop cases, Mach 3, then reads this and tells the machine where to move. Very simple explanation.

The Denfords, Boxfords, Connect series will talk to Mach once the electronics on board have been upgraded.

Can't really advise you on the models as that's not my field but I would have thought a wheel rim would be better turned to shape and then the spoke placements punched in using a small lever punch and a couple of dies in relation to a 4th axis or dividing head for the indexing.

With tyres and Cut3D it would be possible to make a 1/2 mould and with the matching half mould these from a rubber material. I saw an article some while ago that did just this.
