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
PROCESS PLANNINGSelection of production,Establishing the efficient sequence of operationDetermination of changes in formCalculation of the machining timeRequired skill of the operatorWork at minimum cost and maximum productivity.
•Human-machine system is asystem in which the functions of ahuman operator (or a group ofoperators) and a machine areintegrated.•A system as a single entity thatinteract with external environment.

MECHANIZATION ANDAUTOMATIONMechanization means something is done or operated by machinery.Extensions of mechanization of theproduction process is termed as automation.
COMPUTER AIDEDMANUFACTURING (CAM)Implies manufacturing itself ,aided or controlled by computers.ADVANTAGES OF CAM1. Greater design freedom2. Increased productivity3. Greater operating flexibility4. Shorter lead time
COMPUTER INTEGRATEDMANUFACTURING (CIM) SYSTEMThe integration of CAD (computer aided design) and CAM (computer aided manufacturing) systems is called computer integrated manufacturing (IM).CAD + CAM CIM SYSTEM
HUMAN –MACHINEINTERFACEThe way in which man and machine are inter co-ordinated.Eg:man’s eye sight augmented by using microscopes,telescopes …
CONCLUSIONFor better productivity man – machine interface is needed.
