A couple of good machining engineering images I located:

Intro machine shop exercising

I was delighted when Rana encouraged me to take a machine shop class here at Caltech—I’ve wanted to learn machine tools for seemingly forever. Yesterday and these days I produced this useless widget as the initial exercising in the Mechanical Engineering department’s shop "safety course," which included edge and side milling threaded, clearance, and counterbore holes and press-fit and slip-fit pins. Whee! Tomorrow: the lathe.
