In the Computer Aided Quality Inspection (QAC), using Borkman's optical measurement system and powerful detection software, it is easy, fast, accurate and reliable to obtain the complete surface data of the measured object and the data model of the object. Contrast calculation can quickly and accurately detect the position and deformation of the whole and local deformation and deformation, and also give the position and deviation of the hole and the edge. It takes only a few minutes from measurement to giving complete test analysis data. These data are of great significance for the next step of production.
Digital detection applications, goals and benefits
Detecting the entire stamped surface rather than just a surface segment, resulting in more comprehensive and convincing data results.
Position, quantify the deviation and plot the deviation in color coding. .
Qualification of parts is tested: inspection of the original model, inspection of the warehouse and overall sampling during the production process.
Detect the shape, location, and integrity of the borehole.
Detect the size of the edge, the presence or absence of defects, and the presence or absence of dirt.
Deformation caused by material properties, strain, aging, rust, and decay is detected, and literature is generated.
Significantly improve quality and reduce inspection time by early and rapid automatic detection of the original model.
Early detection of disease elimination problems has improved product quality and production efficiency.

Testing process
The entire test is performed automatically in two steps.
1. Using Borkman's 3D scanning digital system smartSCAN 3D-HE and turntable, automatically scan and generate 3D data and feature line data through software OPTOCAT;
2. The measurement software and the model data are automatically compared by the detection software Polyworks / Inspector V11, and the position of the deviation and the specific number of deviations are given and graphically represented by color coding.
1 Digitization and data calculation
The stamped parts to be tested are fixed on the turntable as required, and the entire measurement process is fully automated under computer operation.
Use the smartSCAN 3D-HE system to measure the data and space of the stampings.
Calculate the geometry of the measured object and the graphical processing.
Calculate the stamping edge data and the shape of the hole.
The 3D data (STL) of the scanned object surface is extended to the feature line.
The surface 3D data of the object and the edge data are input into the detection software in the STL format.
2 Complete the inspection with the software Polyworks / Inspector V11
The CAD model data of the object is called up to determine the inspection content and requirements of the CAD model data: the pattern of the feature line, the edge line and the hole, such as the position and diameter of the hole.
The 3D data and the characteristic line data of the scanned object surface are automatically loaded, and the comparison test and the inspection report are automatically generated, and the 2D and 3D color deviation maps are illustrated, and the rational value, the measured value and the deviation value are given in the form of a table.
in conclusion
Through the use of 3D scanning digital system smartSCAN 3D-HE and supporting turntable turnTABLE 20 and powerful matching detection software, it can be realized
The most modern test for the most modern measurements of Audi car connecting parts. Although the amount of data generated by the scan is large, the detection time is short and the test result is complete and accurate.
