Traceable industrial 3D roughness and dimensional measurement using optical 3D microscopy and optical distance sensors

Project: EU project

Project Details


Supporting roughness and dimensional metrology in industry

Optical measuring systems are widespread in surface and coordinate metrology. They are fast, with high resolution, contactless, and non-destructive, but often not traceable due to the complexity of the interaction between the measurand and measuring system.

Project will characterize 3D optical microscopes and coordinate measuring machines (CMM)s with optical point sensors to enable traceable 3D roughness and dimensional measurements.

VTT MIKES will provide a ball bar and bearings for dimensional measurements and surface characterisation as well as characterise its freeform instrument equipped with confocal
microscopy using different calibration standards.

Call 2020: Metrology for Industry

This project has received funding from the EMPIR programme co-financed by the Participating States and from the European Union’s Horizon 2020 research and innovation programme.
