About the Book
All machines are built up of parts made of different materials and by various manufacturing processes. Some parts are cast from metals; some are forged, while others are produced by machining on different kinds of machine tools. Castings and forgings have to be machined before they acquire their proper shape, exact dimensions and surface finish. Forged parts, whether they are to be machined or not, are called forgings. This book describes various technologies used in the forgings.
Although Vulcan’s air/steam hammers were primarily made up of sand castings, several important components were forgings, including ram points, piston rods, and valve stems. This is a reference for the metallurgy and the manufacturing practice of these components.
