  1. 1. PRESENTED BY, JESLINE PETER 3RD SEMESTER M.SC,IF CUSAT
  2. 2. INTRODUCTIONManufacturing 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
  3. 3. PROCESS PLANNINGSelection of production,Establishing the efficient sequence of operationDetermination of changes in formCalculation of the machining timeRequired skill of the operatorWork at minimum cost and maximum productivity.
  4. 4. •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.
  5. 5. CONCEPTUAL FRAMEWORK FORMAN-MACHINE SYSTEM INFORMATION STORAGEINPUT SENSING INFORMATION EFFECTOR OUTPUT PROCESSING INFORMATION FEEDBACK
  6. 6. HUMAN-MACHINE MODELHUMAN MACHINEInputs Inputs Input controlSenses devicesEg:eyes,ears Eg:keyboard,mouse OutputsOutputs Output controlEffectors devices Eg:screen,auditoryEg:hands,voice alerts
  7. 7. Ability of man Ability of machineHuman memory – Machine –lower greater capacity. capacity.Perseverance is low Perseverance isCan apply logic. high.Not working at Cannot apply logic. constant level. Working at constantSpeed of level. production Speed of production requires experience. high.
  8. 8. MECHANIZATION ANDAUTOMATIONMechanization means something is done or operated by machinery.Extensions of mechanization of theproduction process is termed as automation.
  9. 9. 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
  10. 10. COMPUTER INTEGRATEDMANUFACTURING (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
  11. 11. HUMAN –MACHINEINTERFACEThe way in which man and machine are inter co-ordinated.Eg:man’s eye sight augmented by using microscopes,telescopes …
  12. 12. CONCLUSIONFor better productivity man – machine interface is needed.
