4. WHAT IS MANUFACTURING?
From Latin word manu factus
(meaning made by hand)
manufacture -first appeared in 1567
manufacturing – in 1683
-MAKING PRODUCTS FROM RAW
MATERIALS BY VARIOUS PROCESSES,
MACHINERY & OPERATIONS FOLLOWING A
WELL ORGANISED PLAN FOR EACH
ACTIVITY REQUIRED

5. Product- something that is produced.
[Manufacturing Engineering – in U.S.
Production Engineering – in Japan & Europe]
Manufacturing -,a complex activity.
Involves
MATERIALS, CAPITAL, ENERGY, PEOPLE
People, (of various disciplines and skills)
Variety of machinery, equipment
tooling with various levels of automation
(computers etc), Material handling

6. WE-
• Concerned in converting natural resources to
useful products
• Entire discipline of engineering concerned with
this
• Manufacturing- most important – conversion of
raw to useful form
• Earlier methods- use of empirical relationships,
experience, trial and error methods
• But, fast progress cannot be achieved through
trial and error

7. • Continuous struggle for cheaper
production with better quality
• Only through optimal utilization of
material, human resources,
development of newer and better
methods
• Manufacturing which was an
art became a Science

8. • Raw material-
conversion through mining and
metallurgy
Changing the raw material to useful form
through various processes----
Casting; primary and secondary forming;
machining and joining

9. Making a Product
Involves
• Product Design
• Material Selection
• Process Design
• Cost analysis
• Feedbacks and
improvements

10. MANUFACTURING
• CASTING
• FORMING
• JOINING
• MACHINING
In various
sections of
workshops,
you had basic
training during
the first year.

11. • Out of this, this course covers the primary
process of casting, and the processes-
forming and joining.
• More about machining will be taught in
subsequent semesters.

12. Schedule:
