R&D project

Microparts - Multi-sensor metrology for microparts in innovative industrial products

Period of the project

Start: Juni 2013
End:   Mai 2016

Description of the project

The main goal of the project is achieving accurate and traceable multi-sensor measurements of microparts with tactile micro probes, optical sensors and industrial computed tomography and their application in industry.

The main activities are:

  • Realization of tactile probes with very small probing elements (∅ < 100 µm)

  • Reduction of the measurement errors of tactile microprobes, e.g. by area-wise determination of the form deviations of the probing element

  • Reduction of the measurement errors of optical sensors and CT, e.g. correction of systematic errors by numerical modeling and optimization of measurement parameters

  • Evaluation of the object-sensor interaction

  • Development of procedures to ensure the traceability of the measurement results to the SI base unit meter by numerical simulations and workpiece-like reference standards

  • Intelligent data filtering to reduce the size of data sets and the measurement errors

  • Procedures for automated fusion of data sets

  • Demonstration of the project results on important industrial measurement tasks

The three-year project is funded by the European Union within the framework of the „European Metrology Research Programme“ (EMRP) and coordinated by PTB.
