Forging: Principles and Techniques

This lecture covers the principles and techniques of forging, a metal forming process that changes the shape of matter through the application of stresses. Topics include hot forming processes, classification of forming techniques, the role of tool geometry, and the impact of material properties on formability. Various forging methods such as die-forging, precision stamping, and advanced techniques like progressive die-forging are discussed, along with the importance of lubrication and friction in the forging process.
