Cold and Hot Forging: Fundamentals and Applications

Cold and Hot Forging: Fundamentals and Applications is a practical guide to the design and optimization of forging operations and dies. It reviews relevant engineering principles, describing the deformation and flow of materials, the concept of flow stress, and the development and use of flow rules based on Tresca and von Mises criteria. It discusses the issue of heat generation and transfer along with related factors such as die geometry, materials of construction, press speed, contact time, friction, lubrication, and forging temperature. It explains how approximate methods such as finite elements can be used to better understand and more effectively control forging operations and the geometry, tolerances, surface quality, and mechanical properties of forgings. It describes common types of forging machines and their differentiating features and functions. It discusses process and die design, methods for estimating forging loads, and the use of finite element analysis to simulate hot, cold, and warm forging processes. It also covers isothermal and near-net shape forging, die wear, and microstructure modeling. Several chapters include supplementary materials consisting of presentation slides and animations showing the simulation of various forging operations.
