Question regarding Engine Turning by CAD/CAM methods

Has anyone in this forum tried using CNC equipment to produce engine-
turned style engraving?
I am referring to the geometric ("sprial-graph") type engraving
produced on watch/clock dials using antique rose-engine lathes and
straight-line engines.

Examples:

Any thoughts?
I can provide more info on the traditional techniques, referring to
literature.

Thanks,
