A bike hub is mainly turned on a lathe. Spoke holes are drilled and if it's a hub brake or a rear hub there may be some milling too.
Machining process is a broad term that refers to the cutting processes, abrasive processes and the non-traditional machining processes.
a machining process carried out on a workpiece with constant cross-section.
It is a hub.
objectives of magneto abrasive flow machining
forcing abrasives over work piece at higher speed for cutting . it is unconventional machining process .
In the bearings that go between the stationary part - the axle, and the rotating part - the hub.
Annealing.
The adaptive control is basically a feedback system that treats CNC as an internal unit in which the machining variables automatically adapt themselves to the actual conditions of the machining process.

In ordinary machining we use harder tool to work on workpiece , this limitation is overcome by unconventional machining. unconventional machining is directly using some sort of indirect energy for machining. Example : sparks, lasers, heat , chemicals etc.. applied in EDM ,laser cutting machines...etc
SEE; poke-yoke (error proofing) process capability statistical process control
on the rear wheel, at the hub. it's the bit that the chain runs over.
