the book to read if you would like to know is William Henry Rohr . First published in 1919 "machine molder Practice" is considered the bible on grinding and setting up molders.
Rohr also has a book on spindle moulders "Modern shaper practice" and is just as religious.

I copied this from a post I did on Canadian woodworking forum which has lots and it’s archives
An equally good book is Modern Woodworking Machine Practice by J. Raymond Foster
