I like reading about machining from time to time (I posted a couple of old books from the "" free book site).  I encountered this PDF last night, which is more current (1993).  There is a lot of useful information, especially for hobbyists.
Thanks Randy. Lots of useful information in there.

Here is a much better link - there are more illustrations and they are much clearer:

This is a good basic machining text !! Our tax dollars at work !
Here is another one and there are two volumes:
I've posted about the Machinery Repairman books on a number of occasions and they are excellent reference/teaching/learning resources.  In addition the Foundryman and Hull Technician books are equally good for those wanting reference material for casting and welding. 

Given the technical nature of the Navy I'm sure there are also good books covering small engines, diesels, various electronics, hydraulics & pneumatics, electrical and many other technical fields.
That last book series that I posted was written in 1919 as educational material (for apprentices, I suppose) and everything in it is amazingly applicable today.  (For some reason, the author left out CNC machines Jawdrop LOL.)

There is even material about vertical mills, which I thought were a relatively new development, maybe during the 'forties.  (Those described are "real" vertical mills, not just horizontals with a detachable vertical head, although those are also discussed.  They aren't what we call "turret head" mills, however.)

Most surprising to me was that, even in 1919, high speed steel tooling was being used.  I thought that development occurred in the late 'thirties !

Fun reading - the drawings and photos are really cool !
Following up on my HSS comment above, further reading (which names the British and the American metallurgists that developed the alloy) states that HSS has been in use since 1898 !!! Amazing, at least to me !

That's pretty cool. An interesting read indeed. Thanks for sharing Randy.
