PhD position - Electric discharge drilling and electrochemical machining in Zürich

100%, Zurich, temporary

The Institute of Machine Tools and Manufacturing (IWF) at ETH Zurich focuses on fundamental and applied research in many areas of production engineering. Headed by Prof. Dr. Konrad Wegener, the fields of activity range from production machines, manufacturing processes and machine simulation to virtual reality. The IWF works in close cooperation with inspire AG, the leading Swiss competence centre for technology transfer to the mechanical, electrical and metal industries and many other industry partners. To strengthen our process group, we are offering the following position for young scientists (m/f).

Electric discharge machining is one of the most important process technologies for the production of tools, moulds, as well as dies, and enables efficient mass production. Hardly any device of daily life can do without this technology today. Due to the extreme process conditions, temperatures above 10000 K, high spatial and temporal derivations, and multiple phase (dielectric, plasma and melt), the understanding of the processes, which is the basis for process improvement, is still limited. At the IWF, this interesting process has been researched for years and new results are constantly being obtained that are helpful for process optimisation. The aim of this work is to enlarge the potential of EDM drilling to machine aerospace materials and investigate in new applications of EDM and ECDM in this field. Some research has shown ability of ECDM (Electro-chemical discharge machining) to drill through non-conductive materials, such as ceramics. The ability to industrialize this solution could expand EDM application-field, while avoiding delamination of TBC through high-power laser drilling.

You will explore and exploit these innovative processes in close collaboration with a leading OEM manufacturer, which intends to increase hole drilling EDM machine sales using the deliverables from the proposed work. The key value proposition will be the ability to machine cooling holes and seal slots in a single setup, for metallic, ceramic-coated and CMC components, such as Nozzle guide vanes (NGV) and turbine blades.

You meet the requirements for a doctoral programme at ETH Zurich and have a Master's or diploma degree in mechanical engineering, materials engineering, physics or computer science. You are highly motivated and eager to learn. In addition, you like to combine theoretical considerations and models with experimental tasks and would like to be involved in teaching at the IWF. Accurate work and very good communication skills in German and English round off your profile. We offer you a full-time position for the duration of your doctoral studies. Through close cooperation with our project partners you will quickly establish contacts with the Swiss industry. In our young team you will work at the cutting edge of today's knowledge in production and manufacturing technology.
