The Project
 Build a complete Test and Certification Barrel of the Boeing 787
Dreamliner fuselage (The 787 Fuselage team).
 Construct this all composite fuselage as a One Piece Skin-Stinger
Bond Assembly.
 The Barrel, when completely assembled with doors, windows, floors,
etc., will be fatigue tested for FAA Certification.
 Maintain commonality between Boeing, the world wide Partners and
the Suppliers (The Production Readiness Team [PRT]).

Metrology Application
 Metrology challenge: inspect the many surfaces of the Tools
to optimize the as-built condition of each Sub-Assembly
when the entire Tool is assembled
 Model Preparation: Develop models, drive files and
tolerances
 Measurement Tasks:
(using laser radar scanner and laser trackers)
a. Inspect Tools for Quality Assurance
b. Use As-Built data to optimally assemble the tool
c. Measure IML and OML after fuselage is cured
 Provide collection data to optimize the manufacturing
process
 Data used in certification and validation of the
manufacturing processes for the FAA
CMSC 2005
STP - Metrology
 Situation:
New manufacturing processes with shortened flow times
require new methods for quickly analyzing data and
generating feedback.
 Target:
The proposed test program must have fast feedback loops of
the survey data.
 Proposal:
Use scripted measurement plans with Spatial Analyzer’s
common interfaces to metrology systems, thus providing a
closed loop control system with critical component features
to automated product assembly. A Big Button interface for
running the scripts simplifies shop floor implementation while
enabling close process flow control. Embedded process
checks and tolerances enable the script to handle real-world
production assembly processes.

The Target
 Seamless integration of measurement requirements in the
Design/Quality Engineering and Production processes for 787
Fuselage Test Barrels.
 Accurate and concise analysis of the data collected, verified
directly to the digital model.
 Rapid turn-around of collected data to support decision making.
 Understandable reporting of the data to all participating parties,
delivered in a timely/consistent manner.
 Make the measurement results available enterprise-wide on the
internet.
 Future application for partner use on production airplane (digital
portable solution).
 All partners/suppliers use the same digital thread: common tie-in
and verification method yield product consistency across the
supplier/partner chain.
CMSC 2005
The Proposal
 Form a team of metrology experts to script Measurement Plans.
 Script measurement plans and assist in the surveys as needed (the
team).
 Use the same software throughout the process to avoid
misinterpretation of data.
 Use real time analysis capabilities, on screen, so the operator will
know immediately if the data is valid.
 Inspection buy-off can be done ‘on-the-spot’ as the survey is being
taken, or hand stamped on the paper copy of the report, directly to
the design model.
 Generate reports ‘on-the-spot’ and/or send results to a server for
instant observation upon survey completion (avoid delay).
 Share reports enterprise-wide via the internet.
 Use existing tools if possible (SA is currently accredited software in
the Boeing Company).
CMSC 2005
The Plan
(New Method)
 Write integrated Scripted Measurement Plans and Analysis Tasks to
avoid misinterpretation of data.
 Use the same software to write Measurement Plans, perform the
survey and provide analysis.
 Reduce, or eliminate, the time consumed by manual analysis.
 Rapid turn-around of analysis after data collection is complete.
 Work directly with the CAD model.
 Instrument observations, reference tie-in, and measurement
uncertainties are captured, documented and communicated
consistently, establishing a level of confidence in production
deliveries.
