Manufacturing Processesby Rajit Gadh


Traditional tracking in manufacturing processes

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


Problems with today s tracking techniques

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


With rfid what are the applications

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


Manufacturing inventory

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?


Manufacturing inventory1

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


Manufacturing product process status

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


Manufacturing benefits

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


Manufacturing challenges

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


Manufacturing industries impacted

Manufacturing industries impacted

  • Any discrete part - component / assembly industry, E.g.

    • Automotive

    • Aerospace

    • Shipbuilding
