DDI Vintage Jeep Frame Presentation 2008 DDI Vintage Jeep Frame Presentation 2008 Presentation Transcript

  • Reproducing a Jeep BRC-40 with Reverse Engineering Michael Raphael, Direct Dimensions, Inc.
  • Discussion Topics
    • Historical Overview of the Jeep
    • Specific Client Request
    • Identifying the Problem
    • Overview of the Solution: Jeep Frame Case Study
    • Jeep Frame – Review
    • Benefits/Value
    • Summary/Conclusion
  • Historical Overview of the Jeep
    • Original “Jeep” Prototype
    • 1940 American Bantam Car Company pilot model
  • Specific Client Request
    • Measure various parts from antique BRC-40 Jeep frame
    • Parts needed to be completed in an AutoCAD format
    • Accurate models needed so client can duplicate them exactly
    • Specific parts include: frame rails, spring mounts, and “K” cross member
  • Identifying the Problem
    • Original deteriorating frame posed measurement problems because of frame warping and corroded components
    • “Design intent” model needed
    • A combination of the LDI Laser Scanner mounted on a 12’ FARO arm and point probing allowed for accurate data capture
    • Using RapidForm XOR allowed DDI to import all scan and digitizer data and reverse engineer the parts using one software package
    Overview of the Solution: Jeep Frame Case Study
  • Overview of the Solution: Jeep Frame Case Study
  • Overview of the Solution: Jeep Frame Case Study
  • Initial Step – Laser Scanning and Data Capture
    • Scanning the Jeep frame with the LDI Laser Scanner
  • Next Step –Aligning Point Clouds
    • Aligning the captured point clouds in RapidForm
  • Next Step – Mirroring Frame
    • Mirroring and Comparing one side of the frame to the other
  • Next Step – Polygonal Modeling
    • Aligning, cleaning, and filling in holes on the polygonal model
    • Aligning part positions to hole locations and other features
    Next Step – Reverse Engineering Specific Parts
    • Aligning part positions to hole locations and other features
    Next Step – Reverse Engineering Specific Parts
  • Next Step – Reverse Engineering Specific Parts
    • Reverse Engineering and creating specific features from the polygonal and geometric data
    • Continuing to create and align specific parts to the overall rail form
    Next Step – Reverse Engineering Specific Parts
    • Overlaying the “Design Intent” model on top of the completed polygonal model to check for error and inconsistencies
    Next Step – Comparing Captured Polygonal Model to “Design Intent”
  • Final Step – Deliver Requested Models
    • Complete all modeling and deliver the requested models in proper formats
  • Jeep Frame - Review
  • Benefits/Value
    • Because project was completed using one software package, time was not lost translating compatible files between programs
    • Using both a laser scanner and digitizer allowed for a checks/balances and more complete data to build and align parts
  • Summary/Conclusion
    • All parts were modeled to client’s specifications
    • With this “digital archive” client can replicate these parts an infinite amount of times and now has a precise digital record of this frame
    • This method is far more accurate than any other method to measure aged parts
  • Questions?
