Hi:
I was like you, lot's of manual machining, no CNC exposure. I picked up some books to get the theory straight, and then I took the plunge by buying a CNC mill for our workplace (baptism by fire). I never had anyone show me how to do it, but as Jack stated, you already have the machining skills. Also, todays CNC controls are very intuative with @ spindle programming etc. 8 years later (no machining marks on the vises, chucks or tables
), we now have 3 CNC machines humming happily away.
The bottom line: my advise is to "tool up" with the theory (the basics), and then try to find a job doing setup/operating. This will give you some experience. You can move on from there.
