I can remember when I worked for Hawker Aircraft in 1957 that we had a very large machine room using NC controllers. I don't think the technology was all that new, maybe ten years or so? Engineers on the list will have a better idea.

Apparently you are not aware of how numerical contolled machine tools
work. It is a matter of loading the correct program, chucking the
correct piece of metal, and hitting the on button. Once you have the
program, it takes only  ten minutes or so to set up to produce a
particular part.

How old is NC technology?
