OPTICAL METROLOGY

3D digitisation for the fast acquisition of all external geometries:
Optical metrology is suitable in particular for complete component analysis and trend analysis at an early stage on components of any size for process management and quality control. Without contact, quickly and with very high point density, with this method the surface of the component is digitised using a 3D scanner and analysed – in our accredited measuring rooms or directly on site in your premises. The spectrum of components ranges from prototypes, through sheet metal to injection moulded and die-cast components, and battery trays.

POSSIBLE APPLICATIONS AND USAGE
OF OPTICAL METROLOGY

3D digitisation: preparation of a 3D model of the component surface, output of the data as triangulated surfaces (STL data)
Geometric dimensional inspection: highly precise measurement of standard geometries, freeform surfaces as well as shape and position tolerances on very small and large components
Surface comparison: preparation of nominal-actual comparisons against CAD data with any alignment and colour-coded depiction of the deviation
Initial sampling: preparation of initial sample test reports according to drawing requirements (e.g. VDA and PPAP)
Reverse engineering: preparation of CAD models from the scanned STL data, output format of the data: .step and .iges
Measuring volume: variable measuring volume
Mobile ESD protection zone for tests on components sensitive to electrostatic

TECHNICAL EQUIPMENT

We have several systems for optical metrology. Our multisensor coordinate measuring machine combines tactile and optical metrology in one instrument and has white-light sensors for the assessment of surfaces and topography measurement without contact. For holistic component digitisation of medium-sized and large assemblies, we use our highly accurate 3D scanners from GOM.
