The significant use of the micro-scale components in many industries, such as automotive, aerospace and electronic gadgets makes the metrology a bottle-neck technology in manufacturing. Coordinate metrology is the most common way to measure the geometry or form of components. With the developments in visualization (capturing and data processing) and optical technology, optical metrology is becoming more popular for its dense datasets and high precision measurements. So far many optical metrology sensors have been developed and are available in the current market. However, they are difficult to integrate in-line with production machinery.
The main aim of the project is to develop a hybrid-metrology sensor prototype for industrial in-line production measurement systems, including a vision system for fast defect detection and a focus variation system for 3D topography measurement. In practice, the final product would be an industrial in-line production metrology sensor prototype, which is tested with multiple parameters such as measurement speed, system performance, resolution and accuracy. The hybrid system will be integrated with a metal additive manufacturing system.
This project is a part of the Precision Additive Metal Manufacturing (PAM^2) Marie Skłodowska-Curie Innovative Training Network (ITN) funded by the European Union under the Horizon 2020 Programme. PAM^2 has close collaboration with industry and academia to address the quality assurance and the various process stages of AM, with the aim of implementing good precision engineering practice.
