The document provides an overview of key concepts in metal forming including: 1) Metal forming processes use plastic deformation to change the shape of metal workpieces using dies that exceed the metal's yield strength. 2) Material properties like low yield strength and high ductility are desirable and affected by temperature. 3) Processes are classified by the scale of deformation from bulk to sheet metal and include rolling, forging, extrusion, drawing, bending, and shearing. 4) Temperature, strain rate, and friction influence how metal flows during forming. Lubricants are used to reduce friction.
