At what point does smithing become manufacturing

I’ve had a question rolling around in my mind when I watch all sorts of YouTubers and instructional. “At what point does smithing just become manufacturing” I’ve worked aircraft mechanics and manufacturing my adult life and I hobby build cars and black smith so I’m fairly well rounded on both sides. But I find myself saying well I don’t feel as if that’s blacksmithing when I see someone use a mill. I mean I’m no one and this is all just an opinionated thought I have. I wanted your guys opinion if you do the same or what you consider well that’s just manufacturing something.
