The document outlines the classification and selection of manufacturing processes based on their function and production quantity. It describes various process categories, including those for changing physical properties, casting, joining, machining, and surface finishing. Each process is illustrated with examples and specific techniques used to enhance material properties or produce finished products.

3. Classification Based On Function of
Process
 Manufacturing process used in industry
basically performed following purpose…
 Changed the physically properties of work piece.
 Change the shape and size of the work piece.
 Produced desired dimensional accuracy and
surface finish.

work piece.
2) Casting process
3) Primary metal working processes.
4) Shearing and Forming processes.
5) Joining processes.
6) Machining processes.
7) Surface finishing processes.

5. Changing Physical
Properties
 Physical properties of material can be change by heat
treatment like
1) Carbonizing
2) tempering
3) Hardening
By hammering, bending and cold rolling of iron materials and
nonferrous metals a strengthening of the metal structure is changed
systematically. This kind of heat treatment is used for making the
steels hard and wear-resistant for certain purposes.
4) Annealing
The hardness for an annealing process is usually listed on the HRB
scale as a maximum value. It is a process to refine grain size,
improve strength, remove residual stress and affect the
electromagnetic properties.
5) Stress relieving
is a technique to remove or reduce the internal stresses created in
a metal. Stress relieving is usually accomplished by heating a metalaKhTaR kAmAl

6. 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.
 Simple and complicated shapes can be made from any metal
that can be melted.
 Example of cast parts : frames, structural parts, machine
components, engine blocks, valves, pipes, statues, ornamental
artefacts…..

7. Joining Processes
 In this process; two or more metals are joint to each other. Or
repair/join the broken parts.
 The joints are may be permanent like welding OR may be
temporary like Riveting, brazing, soldering…
 Joining process are….
 Screw-Fastening
 Welding
 Riveting
 Brazing
 Soldering

8. Machining Processes
 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.

9. Surface Finishing
Processes
 Surface finishing process are used ensure a smooth surface, to improve
appearance or to provided a protective coating.
 Some of process are like honing and lapping are remove the unwanted
material, there primary aim is to produces a good surface finish.
 Surface finishing operations are as followed…
1) Polishing
2) Honing
3) buffing
4) Barrel Tumbling
5) Lapping
6) electroplating
7) Abrasive belt grinding
8) Inorganic coating
9) Anodizing
