2. Manufacturing processes are the steps through which raw materials
are transformed into a final product. The manufacturing process
begins with the creation of the materials from which the design is
made. These materials are then modified through manufacturing
processes to become the required part.

3. Forming, or metal forming, is the metalworking process of
fashioning metal parts and objects through mechanical
deformation; the work piece is reshaped without adding or
removing material, and its mass remains unchanged.
CHARACTERISTICS:
 Large, heavy and expensive machinery is required.
 Production runs with many parts and steps.

4. FORMING
COMPRESSIVE TENSILE BENDING SHEARING

5. It involves those processes where the primary means of plastic
deformation is done. It includes the following processes:
ROLLING
EXTRUSION
The material is passed through a pair of rollers.
The material is forced through an orifice.

6. DIE FORMING
FORGING
Where the material is stamped by a press around or
onto a die.
Where the material is shaped by localized compressive
forces

7. Tensile forming involves those processes where raw material is
extended to a point till it fractures.
EXPANDING
STRETCHING
Where the tensile load is applied along the longitudinal
axis of the work piece.
Where the circumference of a hollow body is
increased.

8. This category of forming processes involves those operations where it
involves both tensile stresses and compressive loads.
DEEP DRAWING
A flat sheet metal blank is formed into a
hollow body open on one side or a hollow
body is formed into a hollow body with a
smaller cross-section.

9. METAL SPINNING
FLANGE
Basically a metal disk or cylinder is rotated at
high speed by using specially designed tool
through which symmetric product are formed.
It is a process of producing protruding rim,
edge, rib, or collar, as on a wheel or a pipe
shaft, used to strengthen an object, hold it in
place, or attach it to another object.

10. Bending is a manufacturing
process that produces a V-
shape, U-shape, or channel
shape. Similar to other
forming processes it does not
cause any change in the
volume of the material.
Usually this sheet metal bending process can be carried out
cold but may require to heat the metal sometimes.

11. When a great enough shearing
force is applied, the tensile stress in
the material will exceed the ultimate
strength and the material will fail and
separate at the cut location.
Shearing is also known as die cutting and cuts the stock without
the formation of chips or the use of burning or melting. The
process can be performed manually or through electric power.
