This chapter discusses the process of cold forging and its effect on various materials. It describes billet preparation and lubrication procedures, cold upsetting techniques, and the use of slab analysis for estimating cold forging loads. It likewise describes extrusion processes, explaining how to estimate friction and flow stress and predict extrusion loads and energy requirements. The chapter also discusses the tooling used in cold forging, the parameters affecting tool life, and the relative advantages of warm forging.
