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

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.

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.

Various Forging Operations
Coining•Closed-die forging process
•Very high pressure required
•No lubricants
Heading•Upset forging
•Nails, bolt heads, etc.

Piercing•Indenting the surface
•Pressure required is
approximately that of hardness
test
Hubbing

Effect of forging on microstructure
•The formation of a grain structure in forged parts is
elongated in the direction of the deformation.

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

Advantages of Forging
•Hardness and Ductility
•Grain Flow
•Intricate Shapes
Disadvantages of Forging
•High Temperature
•Cost
•Tolerances
•Maintenance
