B5 Safe processes

Quality inspection and logistic quality assurance of micro technical manufacturing processes

In the 3rd phase of funding, the Project B5 aimed at realization of a method for an automated quality inspection of cold formed micro parts. This method was integrated on the existing demonstrator platform. The result was a fast and calibrated 3D-metrology system that can automatically measure deviations of object geometries in a measurement volume of about 1 mm3.  Thereby in addition to deviations from the object geometry, undesired surface imperfections could be detected, which may be within the tolerances but still weaken the structure of the thin-walled components. Thus, the fast acquisition of the micro parts surface turns from a random sample inspection, being developed throughout the 2nd phase, into a 100% inspection.
