Optical system for the measurement of the surface topography of additively manufactured parts (2022)
Journal Article
Vilar, N., Artigas, R., Bermudez, C., Thompson, A., Newton, L., Leach, R., …Carles, G. (2022). Optical system for the measurement of the surface topography of additively manufactured parts. Measurement Science and Technology, 33(10), Article 104001. https://doi.org/10.1088/1361-6501/ac7c5c

Additive manufacturing (AM) is now regularly used for customised fabrication of parts with complex shapes and geometries. However, the large range of relevant scales, high slopes, step-like transitions, undercuts, alternation between dark and overly...

Generation and categorisation of surface texture data using a modified progressively growing adversarial network (2021)
Journal Article
Eastwood, J., Newton, L., Leach, R., & Piano, S. (2022). Generation and categorisation of surface texture data using a modified progressively growing adversarial network. Precision Engineering, 74, 1-11. https://doi.org/10.1016/j.precisioneng.2021.10.020

As machine learning becomes more popular in the precision engineering sector, the need for large datasets of measurement data increases. Due to the often manual, user dependent and labour-intensive measurement processes, collecting a large amount of...

Comparison and validation of surface topography segmentation methods for feature-based characterisation of metal powder bed fusion surfaces (2019)
Journal Article
Newton, L., Senin, N., Smith, B., Chatzivagiannis, E., & Leach, R. (2019). Comparison and validation of surface topography segmentation methods for feature-based characterisation of metal powder bed fusion surfaces. Surface Topography: Metrology and Properties, 7(4), https://doi.org/10.1088/2051-672X/ab520a

Feature-based characterisation, i.e. the characterisation of surface topography based on the isolation of relevant topographic formations (features) and their dimensional assessment, is a developing field of surface texture metrology. Feature-based a... Read More about Comparison and validation of surface topography segmentation methods for feature-based characterisation of metal powder bed fusion surfaces.

Areal topography measurement of metal additive surfaces using focus variation microscopy (2018)
Journal Article
Newton, L., Senin, N., Gomez, C., Danzl, R., Helmli, F., Blunt, L., & Leach, R. (2019). Areal topography measurement of metal additive surfaces using focus variation microscopy. Additive Manufacturing, 25, 365-389. https://doi.org/10.1016/j.addma.2018.11.013

In this work, the performance of a focus variation instrument for measurement of areal topography of metal additive surfaces was investigated. Samples were produced using both laser and electron beam powder bed fusion processes with some of the most...
