This document provides an overview of the ME3102 Manufacturing Science course, which covers casting processes, forming, and joining over four modules totaling 42 hours. The course requires a basic knowledge of materials science and practical workshop classes from the first year. Manufacturing is defined as making products from raw materials through organized processes and operations using machinery. The course will cover primary manufacturing processes like casting as well as forming and joining. Students will be evaluated through assignments, quizzes, and a final exam.

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.
