1 Dimensional Management of Composite Tooling for the World’s Largest One Piece, All Composite Aircraft FuselagePresented by:Craig CramerBoeing 787 Operations Mandrel Production Readiness Leader
2 Composite Solutions Applied Throughout the 787 Aluminum 20%Titanium 15%Fiberglass10%Other5%As you can see, the 787 uses a significant amount of composite materials in its primary structure. This is because composite materials are ideal for an airplane – they don’t corrode or fatigue as metal structure is prone to do.Carbon laminateCarbon sandwichFiberglassAluminumAluminum/steel/titanium pylons
3 The ProjectBuild 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]).
4 Completed Test BarrelThis is one of the earlier experimental barrels build to test composite lay-up techniques. Our certification barrel will be larger than this one.
5 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 assembledModel Preparation: Develop models, drive files and tolerancesMeasurement Tasks:(using laser radar scanner and laser trackers)Inspect Tools for Quality AssuranceUse As-Built data to optimally assemble the toolMeasure IML and OML after fuselage is curedProvide collection data to optimize the manufacturing processData used in certification and validation of the manufacturing processes for the FAA
6 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.

This is a great way to illustrate what you will measure and to get team buying but it cannot be tied directly into the measurement instrument or analysis tools.Step 2:Create the nominal inspection file in CATIA V5 by building planes, points, intersects and vectors on the many surfaces in the engineering model. This will be the file used to create the drive file to run the scanner.Step 3:Send the nominal CATIA file through a translator like IGES of STEP.Step 4:Build the drive files done manually by our best Analysts. Done in Verisurf then converted to Excel for download to the measuring device.Step 5:Inspect the tool using the tracker and scanner run by Spatial Analyzer without a scripted measurement plan. Most of the routines are manually input by or most experienced operators. They are interpreting the plan published in PowerPoint. These are our best people so they do a great job of knowing how and what to measure but again, the input is mostly manual. Believe me these people are great but they have a lot of people trying to back seat drive during the measurement.Step 6:Okay, her is where is gets messy because we are asking our Analysts do crunch a whole lot of data. Our analysts are very good at what they do but they are asked to do a lot of work and are put under a great deal of pressure to kick out the reports. Inevitably, everyone wants a little different analysis or report so the Analyst is being pulled from every direction.Step 7:Generate the many reports that are asked for by the many organizations whishing to look at the data. A monumental task.PowerPointCatiaCatiaExcelThese processes may take several weeks because they are mostly manual inputMEASUREDDATAANALYZEDRESULTSREPORTEDExcel
8 The TargetSeamless 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.
9 The ProposalForm 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).
10 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.The goal here is to give the skilled workforce doing the assignment the tools to do their jobs more affectively and efficiently yielding confidence in the product being measured.

15 Measurement Plan Automation Automated Drive File Creation – Feature BasedOnce the script is written, drive file creation is basically automaticThe pervious method that Boeing has used to create drive files was to construct them in CATIA V5.This method is very time consuming.

17 Completed Barrel with (3) LR200 Scanners Setup #1#3#2The ability to run multiple devises is paramount.It allows the operator more freedom as well as reducing the uncertainty by taking the data from multiple view points.SA will collect the data from multiple machine simultaneously (not waiting for one devise to finish.We can run simulations prior to going to the shop floor to predict devise locations and line of site as well as breaking the data down into sets to streamline the measurement and organize the data that we will report out. The SA scripting commands will re-load the data missed by the pervious shot when the devise is re-positioned for line of site.
