2. Introduction
Classification of manufacturing process
 Classification based on Function of Process
 Classification based on quantity of production

3. Classification Based On Function
of Process:
Casting process
 Forming process
Fabrication process
Metal removing

4. Casting Process
Casting processes basically involve the introduction of a molten metal
in to a mould cavity, where up on solidification, the metal takes on the
shape of the mould cavity.
Example of cast parts : frames, structural parts, machine components,
engine blocks, valves, pipes, statues, ornamental artefacts…..

5. Forming process
Utilizes material that has been cast
Modify the shape, size, and physical properties of the material
Types of forming process :-
 Rolling
 Forging
 Extrusion
 Wire, rod, and tube drawing

6. Fabrication Process
In this process; two or more metals are joint to each other.
Fabrication processes
 Screw-Fastening
 Welding
 Riveting
 Brazing
 Soldering

7. Metal Removal Process
Machining consist of forcing cutting tool with one or more edges
through the excess materials on a work piece and removing this
excess material in the form of chip.
Knurling

8. Classification based on the
quantity of production
Unit wise production
Batch production
Mass production

9. Unit wise production
A type of business model that performs or creates single and
customized projects for a specific client. Job production is
typically performed by skilled experts to a high standard and
usually allows for considerable flexibility and customization in
the finished product.
Example :- Bridges, ships, large airplanes, locomotives, large
machinery

10. Batch wise production
A manufacturing process in which components or goods are
produced in groups (batches) and not in a continuous stream.
Example :- Car production, Bike production

11. Mass production
Mass production is the manufacture of large quantities of
standardized products, frequently utilizing assembly
line technology.
Example :- Liquid, Gas, oil etc.
