3 D Scanning And Reverse Engineering March 2009 3 D Scanning And Reverse Engineering March 2009 Presentation Transcript

  • Non Contact Surface Inspection & reverse engineering By Applications 3D (248) 853 7700 www.applications3d.com Email: [email_address]
  • Intro….
    • Applications 3d is a high tech company based in the Metro Detroit area. Our main focus is in the following areas:
    • Non contact white light 3D scanning
    • Reverse Engineering
    • Surface modeling
    • 3D Inspection
    • Part to CAD comparison
    • Digital Assembly
    • CAD / Native data conversion.
    • Our team of highly skilled and educated professionals have been involved in the Reverse Engineering processes since 1997. We have gone through a variety of hardware and software and now just use the best ones to do the job..
  • The Technology
    • 3D non contact scanning is exactly what it sounds like. It is basically taking pictures of an object by a highly specialized and calibrated digitizing machine. The output is a dense point cloud containing millions of points. Each point has its own xyz coordinates similar to points generated by a CMM machine. The difference is that at no point of time does the digitizing machine or any part of it touch the object. Due to this advantage , soft parts or parts which do not have any fixtures for them can be easily measured.
  • The Technology…
    • White light digitizing is done by the principle of triangulation. The camera has inbuilt CCD sensors and a projector which throws white light onto the object. Since the distance between the CCD sensors and the projector is known, the xyz coordinates of about 4 Million points are calculated in each shot using triangulation algorithms. Since each “shot” or measurement is independent of each other and covers a small area at a time, different shots taken at different angles from the object are “stitched” together by using “photogrammetry”.
  • The Technology…
    • Photogrammetry is the same process which is used by satellites to accurately measure the surface of the earth . It involves attaching retro reflective targets and highly calibrated scale bars on the object and taking pictures with a enhanced digital SLR camera. The output is an xyz list of points which represents the target centers. Using those target centers , all the digitized “shots” are stitched together to form one global point cloud.
    • Photogrammetry itself is a flexible measurement tool . Big and awkward objects can be measured using this method .
  • The Technology…..
    • Our newest scanning hardware, the Steinbichler Comet V- 4M, with mulitiple measuring volumes, high resolution, and automated scanning, the Comet-V has taken the scanning / digitizing process to a new level.
  • Industries Served
    • The applications of this technology are limited by imagination only. Some of the key applications where it is being used is:
    • Tooling Industry( Dies and Molds)
    • Automotive and aerospace
    • Injection molded and stamped parts
    • Casting manufacturers
    • Consumer products
    • Medical and dental
    • Animation, entertainment and virtual reality
    • We are servicing mainly the tooling and the automotive industries.
  • Applications….
    • In the past we have helped our customers in the following areas:
    • Reverse Engineering
    • Surface modeling/ Solid modeling
    • Exterior / Interior Painted Parts
    • Paint/ Lamination deformation on Injection molded parts
    • First article Inspection/Quality Control
    • Checking for warpage or deviation in molded or stamped parts
    • Updating CAD models
    • Viewing problem areas with help of color plots
    • Measurement of stamping dies and molds
    • Transforming clay models into digital models
    • Developing after market products
    • Troubleshooting difficult and hard to measure areas
    • Mold analysis
    • Digital assembly / Mockup
  • Samples of Past Projects Dimensional Inspection reports- Comparison done with existing CAD data- Flexible , customizable and powerful reporting- FAST !
  • Samples of Past Projects Surface texture anamolies – Reflectance plot on 3D Scandata of injection molded part
  • Reverse Engineering of a Automobile Gas Tank. Reverse engineering of a Golf Club. Reverse engineering of an Automobile seat back from Clay model. End result: Design of an Injection molded part. Native data to Catia V5 conversion. End result sketch based parametric models.
  • This pattern was handmade, referencing from a drawing of a Texas themed plastic chair that one of our customers wanted mass produced. The clay pattern was digitized using our scanning technology and the scan data was subsequently converted into a solid model, which was then used to machine the mold.
