Doctoral Candidate (DS) / PhD Position: Development of an Assisting Tool for Electrical Discharge Machining

Technische Universität Chemnitz is offering a fully funded doctoral candidate / PhD position in the Faculty of Mechanical Engineering, Professorship Micromanufacturing Technology, within the MicroMan4Health doctoral network. The project topic is “EDM Machining-State Analysis from Discharge Signal Data” and is focused on developing an assisting tool for electrical discharge machining (EDM) to better understand machining states and deposition characteristics from discharge signal data. The research aims to create a data-driven method for analysing real-time discharge signals, correlating pulse voltage/current signals and discharge behaviour with material removal and surface functionalization, and predicting machining results with improved process stability and fewer experimental iterations. A central application is the integration of antibacterial coating strategies for medical-implant machining and new tool–workpiece material combinations. The position is part of the MicroMan4Health doctoral network, which includes 15 doctoral candidate positions and connects universities and research institutes across several countries, with industrial secondments built into the training structure. The network is funded by the European Union under Horizon Europe / Marie Skłodowska-Curie Actions (Grant Agreement No. 101312169). The advertised role is for 3 years and is stated as a 100% position with salary plus allowances according to MSCA Doctoral Networks rules . Eligibility highlights include a completed Master’s degree or equivalent in Mechanical Engineering, Materials Engineering, Production Engineering, or a closely related science/engineering discipline. Applicants should have experience with experimental research, very good English skills, and strong motivation for interdisciplinary and international collaboration. MSCA mobility rules apply: candidates must not have lived in Germany for more than 12 months in the three years before October 2026, and they must not already hold a PhD. The application deadline is 30 September 2026 . Applications must be submitted via the university’s online portal; email applications will not be considered. Required materials include a motivation letter, academic CV, diplomas, transcripts, an English summary of the Master’s thesis, proof of English proficiency if available, publication list if applicable, and reference details. The position is based at Chemnitz University of Technology in Chemnitz, Germany .

Doctoral Candidate (DC) / PhD Position (m/f/x): Laser-Beam Micromachining for Manufacturing of Moulds for Bio-Analytical Devices

Chemnitz University of Technology is offering a fully funded Doctoral Candidate (DC) / PhD position in the Faculty of Mechanical Engineering, Professorship Micromanufacturing Technology. The project is part of the MicroMan4Health doctoral network and is titled “Laser Beam Micromachining for Point-of-Care Diagnostic Moulds” . The PhD project focuses on laser-beam micromachining for manufacturing moulds for bio-analytical devices , especially point-of-care (POC) diagnostic parts. Research topics include developing advanced laser machining strategies, building a software-supported framework to predict and optimise laser-material interactions, analysing beam-surface interactions, and modelling how pulse characteristics affect accuracy and surface quality. The work aims to deliver reliable ablation datasets, validated laser-scanning optimisation strategies, and a robust process-design methodology for high-quality POC mould production. The position is supervised by Prof. Dr. Andreas Schubert and is embedded in an international network of 15 doctoral candidate positions across universities and research institutes in Europe and the United States. The network emphasises data-centric micromanufacturing for next-generation healthcare and MedTech applications, and includes secondments to industrial and academic partners for validation and round-robin testing. This is a 3-year, full-time, 100% funded position with salary and allowances according to the MSCA Doctoral Networks rules, funded through Horizon Europe (Grant Agreement No. 101312169). The role is intended for further scientific qualification and includes enrolment in the doctoral student programme at Chemnitz University of Technology. Applicants should have a completed Master’s degree or equivalent in Mechanical Engineering, Materials Engineering, Production Engineering, or a closely related science/engineering field. The call also asks for experience with experimental research, very good English, and strong motivation for interdisciplinary and international collaboration. MSCA mobility conditions apply: candidates must not have lived in Germany for more than 12 months in the three years before October 2026 and must not already hold a PhD. The application deadline is 30 September 2026 . Applications must be submitted via the university’s online portal only, using the keyword Microman4Health-DC10-LBM . Required documents include a motivation letter, academic CV, publication list if applicable, copies of diplomas and transcripts, an English summary of the master’s thesis, proof of English proficiency if available, and a reference letter or referee contact details.

Simulation-Assisted Tool Design for Pulsed Electrochemical Machining of Magnetic Shape-Memory Alloys

Shape-memory alloys set high demands on the production technologies being used. During cutting, continuous heat input and mechanical stress have an undesirable influence on the shape-memory effect. Pulsed electrochemical machining (PECM), which is based on anodic dissolution, enables force-free machining without thermomechanical influence on the edge-zone properties of the workpiece. Depending on the desired geometry, the development of a customized PECM fixture is necessary. The design of the fixtures is often based on the experiences of the designers and manufacturers, which often results in an estimation of the functionally critical dimensions. For this reason, the study focuses on a methodical approach for evaluating crucial fixture dimensions using knowledge of the specific material dissolution behavior linked with a numerical simulation model. It has been shown that the shape-memory alloy NiMnGa has a non-linear dissolution behavior in sodium nitrate. A reduction of stray currents up to 20% resulting from a lateral gap between the cathode and electrical insulation was demonstrated using numerical simulation. The study shows that a low cathode shaping height has the strongest influence on precise processing. Varying the process parameters allowed for the lateral gap to be adjusted between 0.15 and 0.25 mm.
