  1. Manufacturing Processesby Rajit Gadh

  2. Traditional tracking in manufacturing processes • Processes used today • Automotive • Aerospace • Common methods – human readable / optical • Bar coded approach • Metal /Plastic I.D. • Embedded/engraved numbers

  3. Problems with today’s tracking techniques • Lack of automation • Manual errors – for human readable • Line of site requirement - Optical • Total cost is far greater due to human labor cost • More time to read numbers

  4. With RFID – what are the applications? • Inventory management – automation • Storing and retrieving product feature status for complex products on the product itself • Process status /check on a product • Entire supply chain

  5. Manufacturing - Inventory • Typical inventory questions • What is the inventory level in storage? • Where is it in the manufacturing floor/warehouse? • Locating an individual inventory item • Is dynamic inventory scheduling possible based on dynamic customer demand? • Technology considerations • Tag range • Interference with other material • How much data is enough?

  6. Manufacturing - Inventory • RFID tags maintain current item information on the tag • Useful for managing production of complex or customized products and assemblies • Eliminate the need for separate paperwork on assembly status and content • R/W requires larger memory tags, e.g., aerospace

  7. Manufacturing – Product/process status • Process completion • Central product database can be notified when each process has been completed • Determine product features • Field personnel would use if no user manual • Date of manufacture, revision levels, etc. • Real-time tracking • Inventory, part kits and sub-assemblies

  8. Manufacturing - Benefits • Benefits • Optimize manufacturing, reduce inventory • Find where parts are sitting/waiting • Get status of part/assembly • Get a finer visibility on what’s happening to in-process inventory (big problem – don’t know exactly where the inventory is when it is in the manufacturing plant) • Workflow monitoring • Process Planning • Automated Inspection

  9. Manufacturing - Challenges • Challenges in Manufacturing • Where do you put the tag? • How do you install it? • Does it replace the Part ID? • How does it behave in the presence of metal in a factory? • Passive/active depends on function

  10. Manufacturing industries impacted • Any discrete part - component / assembly industry, E.g. • Automotive • Aerospace • Shipbuilding
