Yes, I also thought about a force feedback handwheel some time ago. I think BMW pioneered this configurable rotary knob a long time ago. You could program it to have clicks, end stops, freewheeling motion and you could program something like that to give you a feeling of the feed or cutting forces, by forwarding spindle or axis motor current. Like force on a steering wheel or milling machine axis handwheel.
But I checked and force feedback knobs are very hard to find, mostly rare DIY projects with selected (for low cogging) high pole gimbal motors.
But then, an Airbus 320 sidestick does not have force feedback neither...

Force feedback on a mill with ball screws?

If you do climb milling it will pull the wheel by itself, opposed to conventional milling with larger end mills.

Milling with small <2mm bits will break the mill if the feed is not perfect before you will feel anything.

CNC controlled motion is way better than anything you could crank with your hands by feeling.

On small machines a not balanced handwheel will shake the machine in rapid moves (up to 2000rpm on the ball screw)
