Physics-based virtual coherence scanning interferometer for surface measurement (2021)
Journal Article
Su, R., & Leach, R. (2021). Physics-based virtual coherence scanning interferometer for surface measurement. Light: Science and Applications, 2(2), 120-135. https://doi.org/10.37188/lam.2021.009

Virtual instruments provide task-specific uncertainty evaluation in surface and dimensional metrology. We demonstrate the first virtual coherence scanning interferometer that can accurately predict the results from measurements of surfaces with compl...

Analysis of the tribological interaction of a polytetrafluoroethylene-lined radial lip oil seal, shaft and lubricant sample (2021)
Journal Article
Shabbir, S., Garvey, S. D., Dakka, S. M., Rothwell, B. C., Su, R., Leach, R., & Weston, N. (2022). Analysis of the tribological interaction of a polytetrafluoroethylene-lined radial lip oil seal, shaft and lubricant sample. Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 236(1), 123-143. https://doi.org/10.1177/13506501211005876

To investigate the tribological interaction and wear mechanisms of polytetrafluoroethylene-lined radial lip oil seals in service, a sleeve, seal and lubricant sample taken off a rotating rig are studied. The test was terminated at 72 h, after severe... Read More about Analysis of the tribological interaction of a polytetrafluoroethylene-lined radial lip oil seal, shaft and lubricant sample.

Statistical point cloud model to investigate measurement uncertainty in coordinate metrology (2021)
Journal Article
Senin, N., Catalucci, S., Moretti, M., & Leach, R. (2021). Statistical point cloud model to investigate measurement uncertainty in coordinate metrology. Precision Engineering, 70, 44-62. https://doi.org/10.1016/j.precisioneng.2021.01.008

In this work an approach to investigate measurement uncertainty in coordinate metrology is presented, based on fitting Gaussian random fields to high-density point clouds produced by measurement repeats. The fitted field delivers a depiction of the s... Read More about Statistical point cloud model to investigate measurement uncertainty in coordinate metrology.
