I have at least 4 books on milling from the “Workshop Practice” series and the book by Jason, I haven’t got the Crowood book. I have a Sieg SX3 milling machine.
The book by Jason, and his YouTube videos should be first on your list if you have a modern Sieg/Warco/Amadeal mill.
Why?, well it’s the only book that references the higher speeds of the newer mills, along with solid carbide cutters and insert style face milling cutters. The difference between Slot Drills and End Mills has also become somewhat blurred since those books were written. ER collets, Aluminium specific cutters, coated cutters and use of Hole Saws etc. are also not going to be in the older books, they are still worth reading ‘tho.
The older books are generally based around slower speed mills, nothing wrong in that, it’s just a different approach is required, higher cutter speeds & lighter cuts with smaller diameter carbide for instance. Nothing wrong with HSS either.
The Harold Hall book, no.35 in the “Workshop Practice” series is good if you want some tooling projects, but sadly, the B&W photography is not perhaps as good as it could be. The Harold Hall website is still available, and has a LOT of info and Projects. You can find it HERE only as a http site, not https ‘tho, so may need to overide your browser setting.
The speeds and feeds calculator on, “The Little Machine Shop” site is also worth a look, HERE
Enjoy.
