The idea that a true CNC machinist is a "button pusher" is insane. You need to combine more skills together than a typical Bridgeport-Man or prototype machinist. Now please understand me. I am of the breed of a machinist who started sandblasting, brazing, fixing broken things, learing from grumpy old white haired machinists, slowly and slowly learing more about precision grinding, manual machining, set-ups, tooling, etc etc. Started to learn CNC back in 1994 on decade old equipment. Was told by other machinists that I could never do it. Well, that was 16 years ago, and I own my own shop with ( paid for CNC mills and lathes. Still do manual machining & grinding everyday. But to me, you need to have manual machining background and a good deal of experience with tooling and fixturing, yes FIXTURING before you should ever be allowed to turn on any CNC machine tool. Let alone "think" you know how to fixture it, tool it and program the machine. I don't care who you are, You will crash a CNC badly if you do not know EXACTLY, and I stress the word EXACTLY what you are doing.
One more thing. If you gentlemen think that we are going back to the "Bridgeport Mill Line" of manufacturing, you are dreaming.For those who don't know. The Bridgeport Mill Line was when shops/factories had tens, sometimes hundreds of Bridgeport Mills side by side almost as far as the eye could see set up in an operation line. The parts would go from one machine to the next completing each OP. CNC is here to stay. It's best to learn it. I find even small jobs faster to make on a CNC. This way you can also make a few extras with ease. Manual machining has it's place. But if you think that manual wil be king again, you might as well start riding a horse to work.
