INTRODUCTIONManufacturing is the backbone of industrialized nation.

Derived from Latin word ‘manufactus’,means made by hand.

It implies making of goods or articles and providing services to meet the needs of mankind.

PROCESS PLANNINGSelection of production,Establishing the efficient sequence of operation

Determination of changes in formCalculation of the machining timeRequired skill of the operatorWork at minimum cost and maximum productivity.

•Human-machine system is a system in which the functions of a human operator (or a group of operators) and a machine are integrated. •A system as a single entity that interact with external environment.

Ability of manAbility of machine

Human memory –greater capacity.

Perseverance is low

Can apply logic.Not working at

constant level.Speed of

production requires experience.

Machine –lower capacity.

Perseverance is high.

Cannot apply logic.

Working at constant level.

Speed of production high.

MECHANIZATION AND AUTOMATIONMechanization means something is done

or operated by machinery.

Extensions of mechanization of theproduction process is termed as automation.

COMPUTER AIDED MANUFACTURING (CAM)Implies manufacturing itself ,aided or

controlled by computers.

ADVANTAGES OF CAM1.Greater design freedom2.Increased productivity3.Greater operating flexibility4.Shorter lead time

COMPUTER INTEGRATED MANUFACTURING (CIM) SYSTEM The integration of CAD (computer aided design) and CAM (computer aided manufacturing) systems is called computer integrated manufacturing (IM).

CAD + CAM CIM SYSTEM

HUMAN –MACHINE INTERFACEThe way in which man and machine are inter co-ordinated.

Eg:man’s eye sight augmented by using microscopes,telescopes …

CONCLUSION For better productivity man – machine interface is needed.
