Surface texture metrology software testing (Math Surf)
Funding: EPSRC IAA and Digital Surf
Duration: December 2019 – December 2020
Team: Richard Leach, Luke Todhunter
Partners: Digital Surf, NPL
Surface texture parameters, filtration and form removal are important aspects of surface topography characterisation that are widely used in manufacturing industry; texture parameters feature on almost all engineering drawings. The current state of the art in reference parameter calculation software is subject to differing implementations of discrete algorithms which can cause discrepancies validating commercial software. The project seeks to expand upon work completed as part of an EPSRC-funded EngD and Manufacturing Fellowship in which mathematical reference standards were created for areal surface texture parameters that are fully traceable to mathematics and allow for the independent and accurate assessment of commercial software performance. This project will develop mathematical reference standards for profile surface texture parameters, and filtration methods and form removal techniques, completing the surface texture characterisation chain from input data to surface parameters. The result of the project will be a set of reference pairs that can be implemented into the commercial metrology software developed by our industrial partner, Digital Surf and other software providers.
