Results of an industrial survey on the use of surface texture parameters (2017)
Conference Proceeding
Todhunter, L. D., Leach, R., & Lawes, S. (2017). Results of an industrial survey on the use of surface texture parameters.

In 1999, CIRP conducted an industrial survey of the use of surface texture parameters [1]. In the seventeen years since, much has changed, with the most important advancement being the introduction of areal surface texture parameters as described in...

Coherence scanning interferometry for additive manufacture (2017)
Conference Proceeding
Gomez, C., Thompson, A., DiSciacca, J., Lawes, S., & Leach, R. (2017). Coherence scanning interferometry for additive manufacture.

Additive manufacture (AM) of metal components is a rapidly maturing technology; but given the large number of interrelated process parameters, it remains difficult to control to high precision. It has been observed that processing conditions may be a... Read More about Coherence scanning interferometry for additive manufacture.

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...

Measurement of internal surfaces of additively manufactured parts by X-ray computed tomography (2017)
Conference Proceeding
Thompson, A., Körner, L., Senin, N., Lawes, S., Maskery, I., & Leach, R. K. (2017). Measurement of internal surfaces of additively manufactured parts by X-ray computed tomography.

Recent advances in X-ray computed tomography (XCT) have allowed for measurement resolutions approaching the point where XCT can be used for measuring surface topography. These advances make XCT appealing for measuring hard-to-reach or internal surfac... Read More about Measurement of internal surfaces of additively manufactured parts by X-ray computed tomography.

Development of CO2 snow cleaning for in situ cleaning of µCMM stylus tips (2016)
Journal Article
Feng, X., Kinnell, P. K., & Lawes, S. (in press). Development of CO2 snow cleaning for in situ cleaning of µCMM stylus tips. Measurement Science and Technology, 28(1), https://doi.org/10.1088/1361-6501/28/1/015007

Contamination adhered to the surface of a µCMM stylus tip compromises the measurement accuracy of the µCMM system, potentially causing dimensional errors that are over ten times larger than the uncertainty of a modern µCMM. In prior work by the autho... Read More about Development of CO2 snow cleaning for in situ cleaning of µCMM stylus tips.

Contamination of µCMM stylus tips: on-machine inspection (2016)
Conference Proceeding
Feng, X., Lacorne, C., Fernandes, G. Q., Lawes, S., & Kinnell, P. (2016). Contamination of µCMM stylus tips: on-machine inspection.

Contamination adhered to the surface of a µCMM stylus tip significantly impairs the dimensional accuracy of a µCMM system. Regular cleaning of the stylus is essential to minimising the dimensional error but little data exists for determining appropri...

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...
