3D Coordinate measuring technology

he SGS Automotive Testhouse carries out non-contact absolute measurements. In addition to the procedures accredited according to DIN EN ISO 17025, significantly more precise measurements of smaller and finer structures are possible via the GOM measuring cell using robots in order to determine surface defects and deformations caused by weathering or mechanical loads with minimal measurement uncertainty (from 30 µm) on all components.

The procedure is accredited according to DIN EN ISO 17025. In addition to the automated GOM measuring cell, an air-conditioned measuring room is available for reproducible measurements and low measurement uncertainties. The components are also optimally fixed with the Witte clamping system.

Our services for the optical measurement of components

High-resolution, two-dimensional representation of the entire component geometry
Precise detection of small and fine surface structures
Measurement of flexible components such as PU foam or textile materials
Objective assessment of surface defects such as airbag sink marks, dents, dings, tool marks, wear and tear
Assessment of trim and break-outs of sheet metals
Determination of deformation of components due to weathering, temperature or mechanical stress (environmental simulations and mechanical testing in-house possible)
Determination of dimensions, as well as form and position tolerances according to DIN/ ISO and ASME
Series measurements incl. process and machine capability analysis (ANOVA) for initial sampling, quality inspection, conformity analysis, determination of manufacturing tolerances
Virtual assembly for optimisation of moulds/injection moulds or determination of gap dimensions and flushness e.g. glove compartment

There are various possibilities for the evaluation:

False colour representation, pass/fail representation
Sections through the component
Material thickness / draft
Comparison with CAD data
