Metal Forming

Large group of manufacturing processes in which plastic deformation is used to change the shape of metal workpieces

The tool, usually called a die, applies stress that exceed the yield strength of the metal

The metal takes a shape determined by the geometry of the die

Material Properties in Metal Forming

  • Desirable material properties
    • Low yield strength
    • High ductility
  • These properties are affected by temperature:
    • Ductility increases and yield strength decreases when work temperature is raised

Basic Types of Deformation Processes

  1. Bulk deformation
    • Rolling
    • Forging
    • Extrusion
    • Wire and bar drawing
  2. Sheet metalworking
    • Bending
    • Deep drawing
    • Cutting
    • Miscellaneous processes
