A Robotic Re-manufacturing System for High-Value Aerospace Repair and Overhaul

This paper describes the necessary elements for the development of a bespoke robotic welding system. The established industry-academia research partnership and project evolution at The University of Sheffield (UK) from 2006 is highlighted in the joint development of a disruptive platform technology for high-value aerospace re-manufacturing. The design process, funding mechanisms, research and development of key components (vision system, high-speed DAQ, advanced GTAW welding system trials) are described in this paper. The interaction of these key components combined with novel collaborative robotic technology and experienced welding engineers has made possible the construction of a robotic aerospace turbofan compressor blade re-manufacturing system. This industry-academia research intensive collaboration between VBC Instrument Engineering Limited (UK) and The University of Sheffield has received project funding from the Engineering and Physical Sciences Research Council (EPSRC, 2006-2010), the Science and Facilities Technology Council (STFC, 2011-2013) and Innovate-UK with the Aerospace Technology Institute (2014-2018).
