With optical 3D metrology through the lightweight construction process

Bringing lightweight components into series production requires profound knowledge of materials – and that is the crux: The behavior of novel materials and structures is difficult to calculate and production processes are subject to different principles than for metal construction. Researchers at TU Chemnitz are now helping to provide a clearer picture: With the aid of GOM optical 3D metrology, they are able to describe specific material properties, to optimize manufacturing processes and to develop precise-fitting lightweight components for all industrial applications.

Beneficiary of this is, among others, the automobile manufacturer BMW: Taking the BMW 7 Series as an example, the researchers from Chemnitz have designed a technology demonstrator for a roof bow made of fiber-reinforced thermoplastics, which is suitable for cost-effective, large-scale series production compared to the thermoset series component.

TU Chemnitz uses the following GOM systems:

ATOS checks production quality

To check production quality, TU Chemnitz relies on the optical ATOS 3D scanner from GOM, which enables precise full-field object digitization in contrast to point-measurement tactile systems.

ARAMIS tests the load limits of lightweight construction materials

Never far away: the high-precision ARAMIS measuring sensor from GOM, which has been specially designed for 3D motion and deformation analysis.

Deformation measurement with ARGUS

Verification of a draping simulation is performed in many cases with the help of practical tests. The ARGUS measuring system from GOM helps to extensively document the change in shape during forming processes and shows the shearing of the material, is also useful.
