3 D Scanning And Reverse Engineering March 2009

  1. 1. Non Contact Surface Inspection & reverse engineering By Applications 3D (248) 853 7700 www.applications3d.com Email: [email_address]
  2. 2. Intro…. <ul><li>Applications 3d is a high tech company based in the Metro Detroit area. Our main focus is in the following areas: </li></ul><ul><li>Non contact white light 3D scanning </li></ul><ul><li>Reverse Engineering </li></ul><ul><li>Surface modeling </li></ul><ul><li>3D Inspection </li></ul><ul><li>Part to CAD comparison </li></ul><ul><li>Digital Assembly </li></ul><ul><li>CAD / Native data conversion. </li></ul><ul><li>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.. </li></ul>
  3. 3. The Technology <ul><li>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. </li></ul>
  4. 4. The Technology… <ul><li>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”. </li></ul>
  5. 5. The Technology… <ul><li>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. </li></ul><ul><li>Photogrammetry itself is a flexible measurement tool . Big and awkward objects can be measured using this method . </li></ul>
  6. 6. The Technology….. <ul><li>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. </li></ul>
  7. 7. Industries Served <ul><li>The applications of this technology are limited by imagination only. Some of the key applications where it is being used is: </li></ul><ul><li>Tooling Industry( Dies and Molds) </li></ul><ul><li>Automotive and aerospace </li></ul><ul><li>Injection molded and stamped parts </li></ul><ul><li>Casting manufacturers </li></ul><ul><li>Consumer products </li></ul><ul><li>Medical and dental </li></ul><ul><li>Animation, entertainment and virtual reality </li></ul><ul><li>We are servicing mainly the tooling and the automotive industries. </li></ul>
  8. 8. Applications…. <ul><li>In the past we have helped our customers in the following areas: </li></ul><ul><li>Reverse Engineering </li></ul><ul><li>Surface modeling/ Solid modeling </li></ul><ul><li>Exterior / Interior Painted Parts </li></ul><ul><li>Paint/ Lamination deformation on Injection molded parts </li></ul><ul><li>First article Inspection/Quality Control </li></ul><ul><li>Checking for warpage or deviation in molded or stamped parts </li></ul><ul><li>Updating CAD models </li></ul><ul><li>Viewing problem areas with help of color plots </li></ul><ul><li>Measurement of stamping dies and molds </li></ul><ul><li>Transforming clay models into digital models </li></ul><ul><li>Developing after market products </li></ul><ul><li>Troubleshooting difficult and hard to measure areas </li></ul><ul><li>Mold analysis </li></ul><ul><li>Digital assembly / Mockup </li></ul>
  9. 9. Samples of Past Projects Dimensional Inspection reports- Comparison done with existing CAD data- Flexible , customizable and powerful reporting- FAST !
  10. 10. Samples of Past Projects Surface texture anamolies – Reflectance plot on 3D Scandata of injection molded part
  11. 11. 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.
  12. 12. 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.
