Extract surface curvature

Sheet metal part manufacturing requires higher accuracy and shorter lead times for bending processes that are flexible and effective. Understanding the sheet metal surface curvature would reduce the deformation and defect of fresh material that is pulled into the die opening. With the help of GOM ATOS compact 3D scanner, we can scan the sections and curves of the sheetmetal to extract values for surface analysis. These values are useful to detect the surface comparison, surface defect map and material thickness. After scanning, the scan data is imported in 3D reverse engineering software called Geomagic Design X. In the software, we can use the Loft wizard feature to create reference planes and cross-section to draw the surface of the sheetmetal and extract the curvature values. This sheet metal 3D model output is given to the customer in any CAD format.
