Default learning CNC


Looking for recommendations on learning about CNC machines.

Back ground:

I have met a machinist that has quit his day job to open a machine shop here in Delaware. And he is having a struggle. He is okay as a machinist, but not so great as a business man. He has a Bridgeport and a Star milling machine, a gap bed lathe ( I forget the manufacturer but it is about a 15 by 60 size ) a surface grinder, horizontal band saw and a Okuma LB-15 CNC lathe.

The Okuma is why I am posting. It has a intermittent problem which we isolated to a servo amp. But we have very little in the way of documentation.. No schematic or even something that would indicate what the dip switches or status leds mean. Servo Amp boards are about $1000 on Ebay. And he is going to buy one.

But I think he should be thinking of retrofitting new electronics. But he is woefully shy as far as electronics. And I don't know enough to be comfortable doing a retrofit , at least on the Okuma.

So I am looking for advice on learning enough about cnc to be able to do a retrofit. There is a little Logan lathe at the shop that is unused that I could
convert to CNC if that is a good way to learn.

And would love to get a good book on CNC, but so far I have not found that.
