An integrated measurement method for complex micro-scale geometries (2016)
Presentation / Conference Contribution
Rabani, A., Senin, N., Helmli, F., Butler-Smith, P., & Leach, R. K. An integrated measurement method for complex micro-scale geometries. Presented at euspen 16th International Conference & Exhibition

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...

Towards uncertainty in dimensional metrology of surface features for advanced manufacturing (2016)
Presentation / Conference Contribution
Musso, G., Senin, N., Galetto, M., & Leach, R. K. Towards uncertainty in dimensional metrology of surface features for advanced manufacturing. Presented at euspen 16th International Conference & Exhibition

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.

Investigating mechanical characteristics of styli for micro-CMMs (2016)
Presentation / Conference Contribution
Ismail, M., Tseng, K.-Y., Claverley, J. D., Sheu, D.-Y., Chetwynd, D., & Leach, R. K. Investigating mechanical characteristics of styli for micro-CMMs. Presented at euspen 16th International Conference & Exhibition

The mechanical characteristics of styli for micro coordinate measuring machines (micro-CMMs) is of importance because of the major effect the styli have on the performance and capability of micro-CMMs. Previous work has focussed on the design of the...

Phase and fringe order determination in wavelength scanning interferometry (2016)
Journal Article
Moschetti, G., Forbes, A., Leach, R. K., Jiang, X., & O'Connor, D. (2016). Phase and fringe order determination in wavelength scanning interferometry. Optics Express, 24(8), 8997-9012. https://doi.org/10.1364/OE.24.008997

A method to obtain unambiguous surface height measurements using wavelength scanning interferometry with an improved repeatability, comparable to that obtainable using phase shifting interferometry, is reported. Rather than determining the conventio... Read More about Phase and fringe order determination in wavelength scanning interferometry.

Performance assessment of a new variable stiffness probing system for micro-CMMs (2016)
Journal Article
Alblahaihid, K., Kinnell, P., Lawes, S., Desgaches, D., & Leach, R. K. (2016). Performance assessment of a new variable stiffness probing system for micro-CMMs. Sensors, 16(4), Article 492. https://doi.org/10.3390/s16040492

When designing micro-scale tactile probes, a design trade-off must be made between the stiffness and flexibility of the probing element. The probe must be flexible enough to ensure sensitive parts are not damaged during contact, but it must be stiff...

Lack of assurance of quality with additively manufactured (AM) parts is a key technological barrier that prevents manufacturers from adopting AM technologies, especially for high-value applications where component failure cannot be tolerated. Develop... Read More about Review of in-situ process monitoring and in-situ metrology for metal additive manufacturing.

Study of manufacturing and measurement reproducibility on a laser textured structured surface (2016)
Journal Article
