I'm sure you'll find books to order or online courses.
My son is about five years ahead of you. The key for him was to bounce around from shop to shop. You don't want to get one year's experience five times. He has now ran all sorts of CNC mills, lathes, press brakes, lasers, etc. and is extremely experienced in CAD/CAM plus he learned to maintain all the machines he worked on.
He's now landed a GREAT job that pays $27/hour with 8 hours week built in overtime. Now, "green button pushers" (his name for a poor CNC operator) make 10 - 14 per hour even with years of experience in our area.
Just thought I'd share his experience with you.
