  1. 3-D Model Based Manufacturing and Inspection

    Brian Pippenger August 2, 2012
  2. Overview Why MBD ? Risk Benefits Future of MBD-”Smart Models” Quality Information Framework-QIF Summary and conclusion Questions\Comments
  3. Why model based definition ? Move away from 2-D paper drawings Smart 3-D Models PMI GD&T Aerospace, military, automotive NIST developing QIF with DMSC, manufactures and software vendors
  4. Risks to MBD implementation Culture of organization Documentation FAA rules and regulations Advisory circular No: 21-48 Used to describe electronic modeling system If used must be in its entirety Adequate replacement for 2-D paper prints
  5. Concerns when developing an MBD environment Data accessibility Data content Data presentation to standards Data management Data security Data retention
  6. Many benefits to MBD Viewed in a common platform PDF viewer Keep cost down for OEM suppliers and vendors Fully annotated model Defining a common methodology for CAD techniques across internal and external supply chain
  7. Levels of annotation As model develops definition becomes rich with data Will become the standard 2-D paper prints no longer needed Can be made for convenience during transition Annotations to models added in steps
  8. Level 1-minimal annotation Envelope dimensions (overall boundary dimensions of the part) “Block” or profile tolerance as applied to the entire part Material and finish requirements Title block information
  9. Level 2-partial annotation Envelope dimensions “Block” or profile tolerance Material and finish requirements Title block information Non-standard dimensions Site map Critical notes
  10. Level 3-full annotation Envelope dimensions “Block” or profile tolerance Material and finish requirements Title block information Full dimensions Site map Full notes Auxiliary views
  11. MBD working environment Large amount of engineering knowledge captured in model Complete annotated model avoids ambiguities Reverse engineering of legacy products Manufacturing\Inspection programming saving will show significant benefits
  12. Smart models All inclusive data set of product Programming speed increased Interoperability standards being developed Associativity of all entities
  13. Quality Information Framework-QIF DMSC & NIST helping to develop standard Holistic and integrated set of information models QIF development of standards Quality Measurement Plans-QMPlans Quality Measurement Rules-QMRules Quality Measurement Results-QMResults
  14. QIF development Ensure interoperability Any information for manufacture or inspection Semantic connections Provide a platform that is easy for everyone to access and understand
  15. Summary Many transitioning to MBD Collaboration between operations, engineering, and supply chain Reduces labor costs, quality losses Enterprise agility Lower product costs Culture changes top down Model is final normative of part definition
  16. Conclusion Best practices developed and followed All in supply chain need to be on board Communication of intent is vital No surprises Every effort to help all involved Correct path for future business Reliable and accessible data for supply chain
  17. Question\Comments Thank You
