SIS utilizes Coordinate Measuring Machines (CMMs) and other Non Destructive Inspection (NDI) methods such as Laser scanning, Touch Probe, Digital Imaging, and Ultrasonic devices to inspect and analyze parts and objects in various ways.
In comparing the dimensional data to the model/drawing, SIS employs numerous verification methods, especially on parts containing complex, free-flowing surfaces that are difficult to fully capture on a CMM.
To verify CAD surfaces, a physical part can be partially or fully scanned using SIS digital scanning devices.
By comparing the captured point cloud data with the CAD model, a comparative analysis can be performed and a report, with a color map of the differences, generated. This report highlights any deviations, and the values of that deviation, from the referenced CAD model to the original artifact.
If any issues are identified, the CAD model can be adjusted and the comparison repeated until even the most complex surfaces are accurately modeled.
