Transcript of "3D Solid Laser Modeling"

  1. 1. 3d Solid laser modeling<br />Manufacturing Automation<br />December 8th, 2010<br />Presented By: Christopher N. Berry<br />
  2. 2. Introduction<br />3D Solid Laser Modeling is a modern technique used to accurately represent physical objects into the virtual world.<br />Required Tools<br />HD Laser (Picza3D Laser Scanner)<br />Image Processing Technology (Dr. Picza3)<br />CAD Software (SolidWorks)<br />
  3. 3. What is Laser Modeling?<br />Creation of point cloud system representing a geometric surface with a laser beam.<br />Records distance values to the surface within the scanners field of view.<br />The object is then recreated in a “reconstruction” software package.<br />
  4. 4. PICZA 3D Laser Scanner<br />Located in the Bell Hall 4th Floor IE Laboratory<br />
  5. 5. Laser Scanner Mechanics<br />
  6. 6. Data Acquisition<br />Data from laser transmitted to computer via USB.<br />Able to manipulate scan parameters.<br />Resolution Quality<br />Laser Beam Pitch<br />Rotation Angle<br />Object Height<br />
  7. 7. Object Reconstruction<br />Side View<br />Top View<br />
  8. 8. Data Conversion<br />After reconstruction complete, save file format as “.STL”.<br />This allows for post- processing of data in desired CAD program.<br />
  9. 9. Post Processing<br />Used to eliminate scanning errors<br />Increases accuracy of scan<br />Enables reconstructed object to be utilized in CAE platform.<br />
  10. 10. Post Processing Phase 1:Importing Scans into SolidWorks<br />
  11. 11. Enable SolidWorks Add-In “ScanTo3D”<br />Step 1 of 14 <br />
  12. 12. Open File as “Mesh”<br />Step 2 of 14 <br />
  13. 13. View Mesh of Part<br />Step 3 of 14 <br />

  32. 32. Pre-Fill Surface Application<br />
  33. 33. Fill Surface Application<br />
  34. 34. Pre-Fill Surface Application<br />
  35. 35. Pre-Fill Surface Application<br />
  36. 36. Pre-Fill Surface Application<br />
  37. 37. Fill Surface Application<br />

  39. 39. Fill Surface Application<br />
  40. 40. Finalize Desired Surface Fills<br />
  41. 41. Perform Digital Render<br />
  42. 42. What are the Benefits?<br />Save time modeling complex components.<br />Accurate representation of surfaces impossible to achieve with current solid modeling technology.<br />Wood grains, bumpy surfaces, curves, grooves, etc.<br />Allows for better analysis in CAE platforms.<br />Motion simulation, fluid flow analysis, FEA analysis, etc.<br />
  43. 43. What are the Drawbacks?<br />High resolution scans mean large files.<br />Usually post processing required.<br />Requires high end technology<br />RAM<br />RAM limits number of data points that can be created.<br />Processor Speed<br />Determines how long it will take to create surface generation.<br />
