I was wondering if anyone made a large wall chart showing feed and speeds. Something like the large wall charts that show number, letter, and fractional decimal equivalents. I need to get better about using the proper feeds and speed for different metals and figured this would be the best way.

The Smithy tables give vastly different SFMs for milling aluminum vs turning aluminum with HSS cutters. For turning they say 200-300 SFM, but for milling they say 400-1000 SFM. Shouldn't they be the same? Or at least close? For other metals they list, the SFMs aren't exactly the same for turning vs milling, but they are in the same …
