This definitely sounds like a job that you would have to go to a CNC operator course for. Just reading through the article, I doubt anyone could pick up all the skills necessary to do this job from on the job training. You probably need hours in a classroom before you're qualified to work as a CNC operator.
It sounds like it would be worthwhile though. From what I understand, most people that have computer programming type jobs get paid pretty well. They also seem to enjoy a lot of job security, because computers don't seem to be going away anytime soon!
