Professor David Curtis is the Head of Capability for Subtractive Manufacturing at the University of Sheffield’s Advanced Manufacturing Research Centre (AMRC) and holds a Personal Chair in Subtractive Manufacturing. He is a nationally recognised authority on machining science and technology translation, serving as the National Chair of the HVM Catapult’s Technology Special Purpose Group (T-SPG) for Subtractive Manufacturing. In this role, he leads the technology roadmapping effort, strategic foresighting, and research and innovation pipeline to ensure the UK remains a global leader in high-value subtractive manufacturing.
David graduated with an MEng in Mechanical Engineering from the University of Birmingham in 2005 (including a Year in Industry), where he also completed his EPSRC and Rolls-Royce-funded PhD on advanced point grinding technology for aeroengine turbine discs. Joining the AMRC in 2009, he progressed from Project Engineer to Technical Fellow, systematically establishing and scaling world-class research portfolios in Abrasive Machining, Emerging Machining Technology, Machining Science, and Complex Commodity Manufacturing (Aerofoils, Gears, and Transmissions). He is also the UK pioneer for translational research in the machining of Ceramic Matrix Composites (CMCs), successfully bridging low-TRL fundamental material science with high-TRL factory-floor deployment.
As the capability lead for subtractive manufacturing processes and technologies, David directs the unified institutional machining capability, bridging fundamental academic research with immediate industrial exploitation for global Tier-1 aerospace, defense, and energy partners. He is deeply committed to nurturing the next generation of engineering talent; he serves as the AMRC Postgraduate Research (PGR) Lead, directing the doctoral training and research culture for the AMRC's PhD cohort, and is the Co-Director of Innovation for the EPSRC Centre for Doctoral Training in Machining, Assembly, and Digital Engineering for Manufacturing.

- Research interests
-
Professor Curtis’s research lies at the intersection of fundamental machining science and industrial implementation. His work aims to deliver productivity, resilience, and sustainability to the high-value manufacturing sector. His core research interests are structured across three strategic pillars:
Subtractive Processes & Machining Physics
- Advanced Abrasive Processes & Point Grinding: Developing high-performance grinding capabilities, including electroplated superabrasive (cBN) tool surface texture evolution, grit morphology effects, and wheel regenerative dynamics in surface grinding.
- Machining of Advanced & Exotic Materials: Investigating tool-workpiece interactions during the machining of hard-to-cut alloys, superalloys (Inconel 718, titanium), and Ceramic Matrix Composites (CMCs). This includes studying chip formation and the wear mechanisms of advanced tool materials like SiAlON and whisker-reinforced ceramics.
- Non-Conventional & Precision Machining: Advancing non-conventional material removal methods, such as Wire Electrical Discharge Machining (WEDM), and their application in the micro-manufacturing of complex miniature commodities, including gears and aerofoils.
Subtractive Technology & Digitalisation
- Zero-Defect Subtractive Manufacturing: Sizing and characterisation of microstructural surface integrity features and detecting thermally-induced metallurgical defects using non-destructive evaluation (NDE) techniques such as X-ray diffraction (XRD).
- Digital Subtractive Manufacturing & Digital Twins: Developing data-driven modelling techniques, including neural networks for machine tool feedrate and cycle time prediction, and real-time model-based simulations for closed-loop machining control.
- Hybrid Manufacturing Systems: Advancing additive-subtractive interfaces, specifically evaluating mechanical properties and shielding effectiveness in Direct Energy Deposition (DED) of reactive materials (e.g., Ti-6Al-4V, 15-5 PH stainless steel).
Subtractive Implementation & Translational Strategy
- Strategic Foresighting & Roadmapping: Leading the UK’s national roadmapping and strategic investment pipeline for high-value machining in his role as Chair of the HVM Catapult’s Subtractive Manufacturing Technology Special Purpose Group (Tech-SPG).
- Industrial Technology Translation: Developing robust translational pathways to scale fundamental machining science (low TRL) into reliable, high-TRL industrial applications for major aerospace, defence, and energy partners.
- Workforce Development & Doctoral Education: Presiding over doctoral training and research culture as PGR Lead for the AMRC and directing innovation within the EPSRC CDT in Machining, Assembly, and Digital Engineering (MADE4Manufacturing).
