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.
