Metal Forming Process

Metal Forming Process

• It involves deforming a metal plastically into various shapes and sizes under the effect of externally applied forces.

• The stress induced during the deformation process are greater than Yield Strength and less than Fracture Strength of material

• Formability

Metal Forming Process

Classification of Metal Forming Process

• Hot Forming or Hot Working Process (T/Tm<0.3)• Cold Forming or Cold Working Process (T/Tm is 0.3-

0.5)• Warm Forming Process (T/Tm >0.6)

• T-Working Temp• Tm- Melting Temp

Rolling

Hot Rolling

• Flat Rolling – End Product have rectangular cross section

• Shape Rolling - End Product have various cross sectional shape such as I section, channels, angles, square, hexagonal rods and tubes etc.
