To remain competitive European manufacturers strive to make constant improvements in their manufacturing processes. The surface topography of a component part can have a profound effect on the function of the part. This is true across a wide range of industries (such as precision engineering, automotive and medical). It is estimated that surface effects cause 10% of manufactured parts to fail which has financial implications. Optical measuring systems are widespread in surface and coordinate metrology as they are fast, with high resolution, and contactless (aspects that are essential for the factory of the future). Unfortunately, optical measurements are not often used in industry as they are not traceable. This is due to the complexity of the interaction between the object’s surface and measuring system. This project aims to improve the traceability of 3D roughness and dimensional measurements using optical 3D microscopy and optical distance sensors. Data evaluation, and uncertainty estimation methods will be developed, and be made accessible to industry by good practice guides, publications, training courses etc.
