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
- Bulk deformation
- Rolling
- Forging
- Extrusion
- Wire and bar drawing
- Sheet metalworking
- Bending
- Deep drawing
- Cutting
- Miscellaneous processes
