Overview
Why MBD ?
Risk
Benefits
Future of MBD-”Smart Models”
Quality Information Framework-QIF
Summary and conclusion
Questions\Comments
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
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
Concerns when developing an MBD
environment
Data accessibility
Data content
Data presentation to standards
Data management
Data security
Data retention
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
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
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
Level 2-partial annotation
Envelope dimensions
“Block” or profile tolerance
Material and finish requirements
Title block information
Non-standard dimensions
Site map
Critical notes
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
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
Smart models
All inclusive data set of product
Programming speed increased
Interoperability standards being
developed
Associativity of all entities
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
QIF development
Ensure interoperability
Any information for manufacture or
inspection
Semantic connections
Provide a platform that is easy for
everyone to access and understand
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
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
