Focus variation measurement of electron beam melted surfaces (2017)
Conference Proceeding
Newton, L., Senin, N., & Leach, R. (2017). Focus variation measurement of electron beam melted surfaces.

Electron beam melting (EBM) is a promising additive manufacturing process which is seeing increasing use in high value manufacturing sectors such as aerospace [1]. With its layer-by-layer approach, EBM can allow the creation of parts of complex shape... Read More about Focus variation measurement of electron beam melted surfaces.

X-ray computed tomography of additively manufactured metal parts: the effect of magnification and reconstruction sampling on surface topography measurement (2017)
Conference Proceeding
Thompson, A., Körner, L., Senin, N., Lawes, S., Leach, R., & Maskery, I. (2017). X-ray computed tomography of additively manufactured metal parts: the effect of magnification and reconstruction sampling on surface topography measurement.

X-ray computed tomography (XCT) has recently become recognised as a viable method of surface topography measurement for additively manufactured (AM) metal parts [1–5]. AM is capable of producing internal features that are inaccessible to other surfac...

Shape descriptors and statistical classification on areal topography data for tile inspection in tessellated surfaces (2016)
Journal Article
Senin, N., Moretti, M., & Leach, R. K. (2017). Shape descriptors and statistical classification on areal topography data for tile inspection in tessellated surfaces. Measurement, 95, https://doi.org/10.1016/j.measurement.2016.09.044

Verification of conformance to design specifications in production, and identification of defects related to wear or other damage during maintenance, are key metrological aspects that must be addressed for micro-scale tessellated surfaces. A new algo... Read More about Shape descriptors and statistical classification on areal topography data for tile inspection in tessellated surfaces.

Towards uncertainty in dimensional metrology of surface features for advanced manufacturing (2016)
Conference Proceeding
Musso, G., Senin, N., Galetto, M., & Leach, R. K. (2016). Towards uncertainty in dimensional metrology of surface features for advanced manufacturing.

In previous work, an original approach was developed for the dimensional characterisation of surface features on parts and test artefacts, aimed at supporting researchers involved in the study of advanced manufacturing processes. In the approach, met... Read More about Towards uncertainty in dimensional metrology of surface features for advanced manufacturing.

An integrated measurement method for complex micro-scale geometries (2016)
Conference Proceeding
Rabani, A., Senin, N., Helmli, F., Butler-Smith, P., & Leach, R. K. (2016). An integrated measurement method for complex micro-scale geometries.

Micro-scale geometries are becoming commonplace in many high-precision manufacturing applications. Micro-drilling processes, for example, are being employed for producing holes in demanding applications involving fluid transfer, atomisers and micro-m...

Study of manufacturing and measurement reproducibility on a laser textured structured surface (2016)
Journal Article
MacAulay, G. D., Senin, N., Giusca, C. L., & Leach, R. K. (2016). Study of manufacturing and measurement reproducibility on a laser textured structured surface. Measurement, 94, 942-948. https://doi.org/10.1016/j.measurement.2016.03.042

In recent years there has been increasing interest in the use of structured surfaces to provide specific functional performance. Such surfaces often consist of localised micro-scale surface features with predetermined geometries. The performance of t...
