Chapter 11: Presses and Hammers for Cold and Hot Forging

This chapter discusses the design and operation of forging presses and hammers. It covers the most common types of presses, including hydraulic, mechanical, and screw presses, explaining how they work and comparing and contrasting their load and displacement profiles, stroke lengths, ram velocities, and energy and stiffness requirements. It also includes information on gravity- and power-drop hammers and where and how they are typically used.
