For short-range 3D scanning we use mobile 3D scanners, laser scanners or strip projection scanners. Laser scanners from Perceptron, Scanworks V4i and V5. Strip projection scanners from Zeiss (Steinbichler), Comet L3D 5M, approved according to VDI/VDE 2634. With these 3D scanners we can digitalize components of almost all sizes. Depending on the measuring volume, the accuracy of the scanners at short range is between approx. 6 µm and 80 µm (individual scan). The scanners work without contact and can usually scan almost all surfaces without object marks. In the following, the workflow of a scanning process during reverse engineering, from the scanned point cloud via the new CAD model to the geometry control (miscolour analysis), is illustrated.
The scanned point cloud of the object to be digitalized is processed with Geomagic Design X (Rapidform XOR) or Geomagic Studio software to create a CAD model. CAD models are created either by exact surface reconstruction or by parametric reconstruction of the model using a 3D CAD system. Both fall within the concept of reverse engineering. The 3D CAD systems that we employ are PTC Creo (Pro/Engineer) and Autodesk Inventor (other CAD systems on request).
