Optical instruments for measuring surface topography are increasingly being used as coordinate measuring machines (CMMs) to allow them to measure complex three-dimensional components. The student will investigate the use of one such instruments based on the principle of multi-axis coherence scanning interferometry (CSI). The fundamental limitations of the techniques acting as a CMM will be determined and quantified. Specification standards that are applied in the CMM field (e.g. ISO 10360) will be applied, where possible, to multi-axis CSI and, where not possible, new procedures will be developed. Methods for calculating uncertainties with the instrument will be investigated, including the principle of a virtual CMM applying a Monte Carlo technique. A number of case study components will be measured to showcase the methods developed. The project is sponsored by a world-leading instrument manufacturer who will provide state-of-the-art instrumentation for the project.

The student will join the team of a larger project to develop new methods of measurement to be used, in many cases inline, in advanced manufacturing. Several research fellows and students will form the project team and there is scope to apply both experimental and theoretical skills, depending on the student’s first degree topics.

The student must have a high-grade qualification; at least the equivalent of a UK 1^st class degree in an engineering (mechanical/materials), science (physics) or a related discipline. The student must be proficient in both written and spoken English, and possess excellent presentation and communication skills. The student will be expected to publish their results in leading journals and to present them at international conferences.

The PhD studentship will cover full university tuition fees and a tax-free enhanced stipend at the rate of £15,600 per annum, for the duration of the project for UK/EU students. The studentship is expected to start any time in 2015.
