PhD Scholarship in Measurements of 3D Additively Manufactured Surface Texture, Traceability and Uncertainty

University of Huddersfield

Location: Jointly based at the University of Huddersfield and the National Physics Laboratory, London

Closes: 1 June 2018 (23.59, BST)

Project title

Applications are invited from suitably qualified graduates for a PhD scholarship (3 years, full-time plus 12 months writing up) for the joint research program of the EPSRC Future Manufacturing HUB for Advanced Metrology of the University of Huddersfield (UoH) and the National Physics Laboratory (NPL). The EPSRC HUB sets out to create ground breaking embedded metrology and universal metrology informatics systems to be applied throughout the manufacturing value chain as an essential tool to achieve significant growth and productivity gains in UK manufacturing. The NPL is the UK's National Measurement Institute and is a world-leading centre of excellence in developing traceable measurement solutions for industry.

Project description

The measurement of additive manufacturing (AM) as-built surfaces is critical for both the control of additive processes and the verification of product quality. However, AM surface texture, due to its complexities (e.g. high surface roughness, complicated underlying surface form, re-entrant topographical features, sharp local gradients, inconsistent optical properties), posts many challenges to the application of measurement techniques, including tactile, optical and X-ray computed tomography (XCT). The aim of the proposed project is to explore the applicability of various surface texture measurement techniques for AM surfaces and investigate the key factors associated with the traceability and uncertainty of these measurements. Case studies of measurements of AM surface texture and uncertainty evaluation will be developed.

Candidate requirements

This scholarship is open to all UK and EU citizens. Overseas candidates can be considered if they possess strong research ability.

Applicants must:

  1. Hold a high-grade qualification, at least the equivalent of a UK First or 2:1 class degree or MSc with distinction in engineering, mathematics, physics or related disciplines
  2. Be proficient in both written and spoken English, and possess excellent presentation and communication skills
  3. Possess experience and skills in:
    a) metrology data analysis
    b) image processing
    c) matlab and C++ programming

For applicants whose first language or language of instruction is not English you will need to meet the minimum requirements of an English Language qualification (the minimum of IELTS 6.0 overall with no element lower than 5.5, or equivalent will be considered acceptable).

Scholarship details

This scholarship will cover a tax-free stipend of £14,777 (for 2018/19) per annum for 3 years, and tuition fees for 3 years.


The main supervisor for this project is Prof Dame Xiangqian Jiang, with Dr Shan Lou and Prof Paul J Scott also on the supervisory team, who are all based at UoH. The NPL supervisor is Dr Wenjuan Sun.
