Back before nearly every piece of manufacturing equipment shipped with computers and motors, automated equipment was driven by cams; mechanical cams not “Computer Aided Machining.” I saw such a machine when I was a young man. Remembering how impressed I was watching this machine execute a dozen or so movements all driven by a single cam shaft with multiple cams, I set out on a video search for footage of such machines. After way too many hours this is the best I could find. It’s footage of a vintage multi-spindle lathe from a now-defunct machine shop in the UK.
It might not be as exciting as watching a 5-axis machine cut a motocross helmet from a block of aluminum, but at about 90 seconds in you can see one of the cam shafts driving some movement. There is a good overview shot at about 2:01 and an interesting close-up on about 5 axes of movement at about the 2:30 mark. There are 7:15 minutes altogether with footage of a few machines.
