I'm looking into a Taig cnc mill to do prototyping/ small production machining.

I'm curious how it handles arcs without a consistent radius ie: generated by bezier or vector spline in cad.
(done a lot of googling to no avail)

I'm wondering if some machines, software, etc do better in this regard, or
if in any cnc platform, nonconcentric curves must be broken down into a series of concentric ones.

Thanks and any knowledge very much appreciated
