This document discusses manufacturing processes. It defines manufacturing as converting raw materials into products using various equipment, processes and manpower. Manufacturing is classified as primary, secondary and tertiary industries. Manufacturing processes are classified into five main types: forming processes shape raw materials, moulding processes use moulds to form shapes, machining processes cut away material, assembly processes join parts together, and finishing processes improve the surface.

3. DEFINITION
What is “Manufacturing”?
 “the process of converting Raw materials into products.”
 The word “manufacturing” is delivered from the Latin manu
factus, meaning made by hand.
 “the conversion of stuff into things” – (by DeGramon, 1998)
 “economic terms for making goods and services available to
satisfy customer”– (by T. Black, 1991)
Prof. P.B. Borakhede, MGI-COET, Shegaon

4.  In modern context manufacturing can be defined as-
 “Making a product from raw material using various
equipments, processes, operations and manpower
according to detailed plan”.
 During processes, the raw material undergoes changes
to allow it to become a part of products.
Prof. P.B. Borakhede, MGI-COET, Shegaon

5. TYPES OF MANUFACTURING
Manufacturing can be defined two ways:
1. Technology –
 This process to accomplish manufacturing involve a
combination of machinery, tools, power and manual
labor.
 Manufacturing also includes the assembly of multiple
parts to make products.

7. 2. Economic –
Manufacturing is the transformation of materials into
items of greater value by means one or more processing
involve.
Therefore, manufacturing is “added value” to the
material.
- “Added Value” – by changing the material’s shape or
properties or by combining it with other materials that
have been similarly altered.

10. TYPES OF INDUSTRIES
 Primary Industry-
Those industries who cultivate and exploit natural
resources are primary industries.
 Secondary Industry-
These industries takes outputs of primary industries
and convert them into consumer and capital goods.
 Tertiary Industry-
These industries constitutes with service sector of
the economy.

13. CLASSIFICATION OF MANUFACTURING
PROCESSES
Manufacturing processes are classified as follows:
 Forming Processes
 Moulding Processes
 Machining Processes
 Assembly Processes
 Finishing Processes
Prof. P.B. Borakhede, MGI-COET, Shegaon

14. 1. Forming Process:-
 In the metal industry, some of the primary forming
operations may take place such as the rolling of basic
shapes in steel, aluminum etc.
 Some of the common shapes so obtained from these
processes are bars, sheets, billets, I-beams etc. Which
are standard shapes.
 These shapes can be used for further processing.
Prof. P.B. Borakhede, MGI-COET, Shegaon

15. 2. Moulding Processes
 Some products require moulding processes such as
sand casting, die-casting etc. to get basic shape or form
which may or may not require further processing.
 The selection of the particular process will depend upon
to size of the job, quantity to be produced, accuracy,
and complexity desired and economy.
Prof. P.B. Borakhede, MGI-COET, Shegaon

16. 3. Machining Process
Metal machining is accomplished through basic
machine tool processes which involve the generation of
cylindrical surfaces, flat surfaces, complex curves and
holes.
The examples of such processes are: turning, shaping,
drilling, boring, grinding etc.
In these machining operations metal is removed from
the part in the form of small chips by the cutting action
of tool.
The cutting action is accomplished by either rotating or
reciprocating action of the tool relating to the part.

18. 4. Assembly / Joining Process:
 These processes assemble the parts and materials
using welding, riveting, soldering, brazing, mechanical
fastening and adhesive joining etc.

19. 5. Finishing Processes:
 These processes are carried out to achieve accuracy,
surface finish or to increase life of the product.
 Such processes include cleaning, blasting, deburring,
puffing, honing, lapping, polishing, painting etc.
