This is a PhD Scholarship jointly funded by the MTC and the UoB. The outline description of the PhD research is provided below. It is expected that the PhD student will spend some time at the MTC in order to ensure engagement and drive value for the MTC and the University of Birmingham. The research will be carried out on state-of-the-art laser processing systems both at the MTC and also at the UoB. The PhD project will be focused on addressing the specific requirements of the MTC industry members that will be agreed with them in the 1st year of this PhD project. For further information and enquiries please contact Prof. Stefan Dimov, s.s.dimov@bham.ac.uk .
Project brief
Laser machining (cutting/drilling/blind-machining) of metals and alloys are extensively used in high-value manufacturing for various applications. Recently, there has been an increased interest on laser machining of advanced materials, in applications like zero-emission transportation, low-carbon energy and clean aerospace. The current expertise and knowledge on laser machining is predominantly based on long-pulse (continuous wave to millisecond) laser focusing on conventional metals and alloys, with very little information available in the public domain on ultra-short pulse laser machining (picosecond (ps)) of advanced materials. The initial work at the MTC on this topic proved that several technical aspects need to be understood to exploit the benefit of ultra-short pulse laser machining process. In this context, this PhD will focus on generating fundamental and applied knowledge, and expertise on ultra-short pulse laser machining. The research will focus on both nozzle based and multi-axis (optical/galvos and mechanical) beam delivery and the use of burst mode processing. The PhD project will also include some elements of process monitoring and modelling/simulation.
The project will build on the results of recently completed H2020 and industry funded programmes at MTC and the UoB. In addition, the PhD project is expected to involve and be relevant to some MTC member companies, e.g. Rolls-Royse, IPG, DMG-MORI, BAE Systems and Synova. In addition, the PhD project will benefit from the capital investment at the UoB in a multi-axis laser micro processing system as part of the ESIF SmartFub project.

PhD candidate specification
The successful applicant will have studied Mechanical, Materials or Manufacturing Engineering, Applied Physics or a closely related discipline. A good knowledge or demonstrated awareness of fundamental aspects of laser-material processing and applied knowledge in laser processing is desirable. Experience in using a range of technologies/techniques for surface characterisation would be an advantage. Candidates should have a BEng or BSc with a master’s degree or a MEng undergraduate degree. The ideal candidate will have a first-class undergraduate degree and/or a distinction at master’s level with first class project work.
