Ok, so you do at least know the machinery. My point was that it wasn't as simple as someone just loading a workflow onto a mill and pressing go. Workholding, zeroing, probing, tool offsets, and all the little setup stuff. Takes someone with experience to get going. Most times, the first time running, a program doesn't work, or at least doesn't work correctly. It is totally possible to setup a machine with a bar feeder and a robot to make finished parts all day long. Getting it to do it correctly and accurately is the trick.
