The first NC machines were punch card driven and used to make stuff like propellers and rotors for turbines after WWII. The National Museum of Scotland in Edinburgh has a Ferranti mill [1] on display that produced radar wave guides in the 50's along with an example of its output [2]. It must have been like alien tech at the time, but still not CNC and extremely rudimentary compared to the machining center in that video. Computer NC was born in the late 1950's. 1: https://www.nms.ac.uk/explore-our-collections/collection-search-results/milling-machine-ferranti/218009 https://www.nms.ac.uk/explore-our-collections/collection-sea... 2: https://www.nms.ac.uk/explore-our-collections/collection-search-results/radar-wave-guide-half-test-piece/325506 https://www.nms.ac.uk/explore-our-collections/collection-sea...
