Why don't you start with the programming manual for your machine? Get it
here if your shop has lost it. I'd learn the maintenance manual too.

For what you're doing, I'd learn to program at the machine and not mess with
ACAD, MCAM etc. to start with.(HUGE larning curve here) Any chance you can
find a local vo-tech that offers CNC training? Iv'e also seen on-line
machine CNC training.
