2. A deformation process in which the material is
compressed between dies, using impact or gradual
pressure to form the part
Make or shape (a metal object) by heating it in a
fire or furnace and hammering it.
FORGING
PREPARED BY : DEVANSU KHORASIYA(GIT-150120119066)

3. Forging is one of the oldest known metal
working process
The art of forging is least 4000 BC and probably
earlier. Metals such as bronze and iron were
forged by early man to produce hand tools and
weapons for war

CLASSIFICATION OF FORGING
PREPARED BY : DEVANSU KHORASIYA(GIT-150120119066)

5. OPEN-DIE FORGING
 Also Called Flat Die and Smith Die Forging.
 Hot forging
 Uses simple and inexpensive dies
 Limited to simple shapes
 Number of components to be forged is too
small
Flat-Die Forging
PREPARED BY : DEVANSU KHORASIYA(GIT-150120119066)

6. OPEN DIE FORGING
Advantages:-
-Simple, inexpensive dies.
-wide range of sizes.
-good strength.
Limitations:-
-Simple shapes only.
-machining necessary.
-low production rate.
-poor utilization of material.
-high skill required.

7. CLOSED DIE FORGING
Also called impression-die forging compresses the
material into the shape of the die cavity
PREPARED BY : DEVANSU KHORASIYA(GIT-150120119066)

8. IMPRESSION-DIE AND CLOSED-
DIE FORGING
 Impression-Die
Takes shape of die cavity
Forms a flash
 Performing Operations
Fullering- material
distribute away
Edging- material gathered
into localized area
PREPARED BY : DEVANSU KHORASIYA(GIT-150120119066)

9. CLOSED DIE FORGING
Advantages:-
-Good utilization of material.
-Good dimensional accuracy.
-High production rate.
-Good reproducibility.
Limitations:-
-High die cost for small
quantities.
-Machining often necessary.

10. ROLL FORGING
Roll forging is a process where round or flat bar
stock is reduced in thickness and increased in
length. Roll forging is performed using two
cylindrical or semi-cylindrical rolls, each containing
one or more shaped grooves
