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.
