    2. 2. Content:-  Introduction  Component of F.M.S Processing Station Material Handling Computer Control  Levels of Flexibility  Types of F.M.S Layout  Objectives of F.M.S by-ranjeetnitj@gmail.com (NIT Jalandhar)
    3. 3. by-ranjeetnitj@gmail.com (NIT Jalandhar)What is F.M.S ?-A flexible Manufacturing System (F.M.S) is anarrangement of machines ,interconnected by atransport system . The transport carries work to themachine on pallets or other interface units so thework-machine registration on is accurate , rapidand automatic. OR-F.M.S consist of a group of Processing workStations interconnected by means of an automatedmaterial handling and storage system andcontrolled by integrated Computer Control .
    4. 4. In manufacturing flexibility means-The Capability of Producing Different partswithout major retooling.A measure of of how fast the company convertsits process(es) From making an old line ofproduct to produce a new product.The ability to change a production schedule ,tomodify a part or to handle multiple parts.So a flexible manufacturing system is amanufacturing system in which there is someamount of flexibility that allows the system toreact in the case of changes whether predicted orunpredicted. by-ranjeetnitj@gmail.com (NIT Jalandhar)

    12. 12. Load and Unload Station:-as identifies from thename load and unload station are used forloading and unloading of work parts in the F.M.S.The various Feature of Load and Unload stationsare:--It act as a physical interface between the F.M.Sand rest of the Factory.-Raw work parts enter the system at load station,while finished work parts exit at unload station-Manual loading/unloading is more prevalent by-ranjeetnitj@gmail.com (NIT Jalandhar)
    13. 13. 2. Automated Material Handling & Storage System:- The various Automated material handling system are used to transport work parts and subassembly parts between the processing station .The other function of automatic material handling and storage system are:- Random and Independent movement of work parts between processing stations. Handling of variety of work part configuration Temporary storage Convenient access for Loading and unloading by-ranjeetnitj@gmail.com (NIT Jalandhar)
    14. 14. by-ranjeetnitj@gmail.com (NIT Jalandhar)For automated material handling and storage ofwork parts is done by A.G.V(Automated GuidedVehicles),A.S.R.S & Conveyors . we are describingA.G.V Below:-Automated Guided Vehicle:-Automated GuidedVehicles (AGVs) are vehicles that are equipped withautomatic guidance systems and are capable offollowing prescribed paths. Unlike traditionalrobots, AGVs are not manipulators, they aredriverless vehicles that are programmed to followa guide path. In automated factories and facilitiesAGV’s move pallets and containers. In offices theymay be used to deliver and pick up the mail.
    15. 15. Features of A.G.V:-It transport material from loading to unloadingstation.It Reduces labor cost.Highly flexible ,intelligent and versatilematerial handling system.Because it is driverless vehicle so it is safe & moreaccurate. by-ranjeetnitj@gmail.com (NIT Jalandhar)
    16. 16. Types Of A.G.V:-There are many types of A.G.V but3 are basic types describe below:-AGVS Towing Vehicles  :-it was the first typeintroduced and are still a very popular type today.Towing vehicles can pull a multitude of trailertypes and have capacities ranging from 8,000pounds to 60,000 pounds and are usually mannedby an operator who adds and removes the trailersat designated stops.AGVS Unit Load Vehicles  :-these are equippedwith decks, which permit unit load transportationand often automatic load transfer. The decks caneither be lift and lower type, powered of non-powered roller, chain or belt decks or custom decks. by-ranjeetnitj@gmail.com (NIT Jalandhar)
