The format used for this project was STEP

Computer Aided Design, Manufacturing & Measurement Integration August Coordinate Measurement System Committee Albuquerque, New Mexico Richey-McIvor-Sandwith Measurements System Integration Challenges Boeing uses different types of CAMS for tool construction and maintenance which are controlled by 2D drawings. Operators are not trained to operate all of the different measurement systems. Operating software and data analysis varies significantly between systems, even for like kind technologies. Measurements System Integration Solution A key to the success of this project was software which provided a common instrument interface, simultaneous and synchronsis data acquisition from different measurement instruments.

Computer Aided Design, Manufacturing & Measurement Integration August Coordinate Measurement System Committee Albuquerque, New Mexico Richey-McIvor-Sandwith Measurement and Assembly Dynamic real time graphical interface shows the measured location of the part against the CAD model. Easy to make adjustments with confidence. Distributed Computing Capable (real-time multi-task measurement and analysis across multiple computers) Synchronous Measurement between Instruments (Master-Slave or Synchronous Polled Modes) TCP/IP interfaces to instruments to enable distributed processing Supports remote process control and monitoring.

Computer Aided Design, Manufacturing & Measurement Integration August Coordinate Measurement System Committee Albuquerque, New Mexico Richey-McIvor-Sandwith Project Specifics Using a 3D CAD model; build components onto a wing spar web in tolerance with minimal tooling and CAMS equipment CAMS equipment consisted of two different manufacturers laser trackers and a PCMM “Tooling” consisted of movable steel stanchions and wooden wedges

Computer Aided Design, Manufacturing & Measurement Integration August Coordinate Measurement System Committee Albuquerque, New Mexico Richey-McIvor-Sandwith Registration/Transformation Example: The tracker on the “wet” (i.e., fuel) side of the spar web measured reference holes on the spar and was best-fit transform to the spars coordinate frame. The tracker on the “dry” side of the web was oriented to the spar’s model by best fitting measurements of web, chord, and ribs features to the spar’s CAD model on the shop floor. The PCMM measurements of reference features on the spar were used to transform it into the spar system. The PCMM could of just as easily transformed into the coordinate system established by the tracker on the “wet” side.
