Not CNC, but making parts for a cnc machine with a manual mill with powerfeed 
Yeah that’s what I did here. I’ve no plans for converting my milling machine to CNC any time too soon either. For what I use my mill for CNC would not help me any.
Same with my lathe. Probably half the time it is off. So usefull for holding, centering, aligning. Great for compressing springs ect
