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

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