The first NC machine tool, which was demonstrated at the Massachusetts Institute of Technology in 1952.
Modern 5-axis CNC milling machines is why the classical machines tools such as lathes, planners, shapers, boring machines, etc are now obsolete. Now you mount a hunk of metal in the machine, close the lid, and push start on the control panel assume the correct numerical control instructions have already been uploaded. You probably sometimes have to change or sharpen the tool bit.
The development of 3D-printing may make milling machines obsolete.
