Vacancy Information – Applications are invited for a fully funded 4-year EngD studentship covering UK fees and stipend /EU fees only, as part of The EPSRC sponsored AMRC Industrial Doctorate Centre (IDC).

A fundamental knowledge gap has been identified where by current tribological laboratory based tests used in industry (e.g. Reichart, 4-ball, tapping torque) to evaluate the performance of metalworking fluids (MWF) prior to commercial exploitation, has been found to have little to no correlation with real machining processes. Due to this mismatch in performance, this leads to MWF suppliers undertaking costly demonstrator / validation cutting trials to determine the fluids performance.

Italmatch aim to develop an equivalent, low-cost machining based test method within a laboratory environment, which can fundamentally replicate the behaviour or characteristics of production based cutting processes. The fundamental behaviour and results observed from these trials can be later replicated and investigated on actual machining/milling trials.

There remains a gap in the understanding of why and how certain additives increase performance and fluid life within a MWF formulation. In addition, there is a lack in understanding the interactions of MWF additives with materials and surfaces within the cutting zone. Better tool life and surface quality can be achieved using certain additives. It is therefore important to understand the tribochemical and tribological behaviours between additives and surfaces. The ability to characterise and understand these interactions will allow the opportunity to optimise the chemistry of the additive formulation to achieve the best results. There will be an opportunity to analyse and compare tribofilm formation on tribometer test samples and actual cutting inserts. This could also lead to developing cost models to optimise cost along with machining outputs, such as tool life, surface finish, cutting forces.

All applications should be submitted online. See the How to Apply section of the IDC in Machining Science website. Please follow the instructions carefully, and ensure that you specify which project you are applying for and include in your statement why you are interested in the project and how you will contribute.

Applicants must have, or expect to get, a 1st or good 2:1 degree (or Masters with Merit) in a relevant science or engineering subject such as Mechanical Engineering, Aerospace Engineering, Materials Science, or Physics.

Due to EPSRC residency requirements, this project is open only to UK and EU applicants who have been resident in the UK for at least 3 years immediately preceding the start of the course. Applicants must meet EPSRC eligibility requirements found here

Candidates must also be able show that their English language proficiency is at a level which allows them to successfully complete the EngD. All applicants require an English language qualification, typically a GCSE or an IELTS test (a score of 7 or above is required, with a minimum of 6 in each component).
