I've been a machinist (vertical mill/Bridgeport) for several years now and while I think I'm pretty good at it, (at least the boss has no complaints) I've had no formal education in machining/metalworking and everything I know has been learned on-the-job from more experienced machinists (who all learned on-the-job also).
Wanting to expand my knowledge of metalworking (and increase my value to my employer/future employers) but not having to time to get the schooling, I was thinking about building up my own "machinist's library".
I'd like to eventually have a collection of metalworking books ranging from basic high school machine shop type text books up to specialized books concerning CNC programming, shop management, metallurgy, shop math, welding, machine repair, ect, ect, ect.
After looking thru several catalogs from supply companies I see there are all kinds of books available but they're quite expensive and the descriptions of the book's contents are seriously lacking.
So what kinds of machining books do you have and which would you recommend? And while I'm at it, any good web sites related to the industry?
