  5. 5.  Classification of Forging processes  By equipment 1) Forging hammer or drop hammer 2) Press forging  By process 1) Open Die Forgings or Hand forgings 2) Closed - die forging or Impression Die Forgings
  6. 6.  Open Die Forgings or Hand forgings •Is the simplest forging process •In open die forging, the metal is compressed by repeated blows by a mechanical hammer and shape is manipulated manually.
  7. 7.  Closed - die forging or Impression Die Forgings •In closed die forging, the desired configuration is obtained by squeezing the workpiece between two shaped and closed dies.
  8. 8.  Various Forging Operations Coining •Closed-die forging process •Very high pressure required •No lubricants Heading •Upset forging •Nails, bolt heads, etc.
  9. 9.  Piercing •Indenting the surface •Pressure required is approximately that of hardness test  Hubbing  Various Forging Operations
  10. 10.  Effect of forging on microstructure •The formation of a grain structure in forged parts is elongated in the direction of the deformation.
  11. 11.  Orientation of Grains Castings Forgings Cast structure Fibre structure in forged steels
  12. 12.  Flow lines in Forging
  13. 13.  Forging a rod, Fullering and Edging a) Stages in forging a connecting rod for an internal combustion engine b) Fullering c) Edging operations to properly distribute the material when preshaping the blanck for forging
  14. 14.  Outline of Forging and Related Operations
  15. 15.  Advantages of Forging •Hardness and Ductility •Grain Flow •Intricate Shapes  Disadvantages of Forging •High Temperature •Cost •Tolerances •Maintenance
  16. 16.  Forged components for automotive applications
