Project Description

Start Date: 1st September 2016
Stipend: Tax free stipend of £18,000 per year, plus all tuition fees paid at UK/EU rates.

Project details
As a new generation of aerospace metallics emerges to meet the demands of future operational performance, so does the challenge to manufacture these metallics efficiently. The machining of these materials is one such efficiency challenge. Although there are many new tools available for the process modelling and simulation of the material behaviour, there are still many gaps in the synthesis, application and optimisation of these systems which limits the proposed manufacturability benefits of new materials and alloys.

Rolls-Royce and Timet are jointly sponsored this EngD position to provide much-needed research focus and progression of this subject area.

The objective of this study is to investigate the range of applicable modelling systems and technologies, old and new, to provide an effective comparative assessment and selection mechanism for their development and utilisation in next generation material machining applications. These processes need to be thoroughly investigated in regard to their output (life, cost, quality) performance, key process variables, operational modes and eventual application in mature and representative case studies which reflect the service intent of these technologies commercially. Within scope are conventional machining technologies (eg milling, turning and drilling) and an applicable range of complex, high performance materials (nickel and titanium alloys) with product applications to the highest specifications and within the most challenging operating environments.

The key areas of investigation will be:

1) Comprehensive benchmarking and analysis of existing and new modelling and simulation approaches for the relevant fields of interest (material & alloy design, processing and manufacture, machining and surface generation).
2) Assessment of technology gaps in fundamental understanding, control, validation and application.
3) Assessment of optimisation routes for selected technologies in future materials and product applications with respect to:
a) Optimisation of material design for manufacture.
b) Optimisation of finish machined surface condition.
c) Optimisation of chip morphology to support evacuation and management of waste within the machining system.
d) Optimisation of cutting tooling design and application.
