Metrology-driven Prognostics for Autonomous Manufacturing Control

Metrology-driven Prognostics for Autonomous Manufacturing Control

Grant Reference: EP/Z53285X/1 (EPSRC)

Funded by the EPSRC, this flagship hub is building the world’s first universal, quality-driven autonomous manufacturing control architecture. Our multi-stage research fuses physics-based models, machine learning, and traceable dual-comb LiDAR measurements to achieve evolutionary, self-learning machine self-calibration while cutting through-life manufacturing energy costs.

This project (in collaboration with Herriot-Watt University and Queen’s University Belfast) will establish and validate methods to assure any high-quality data sources (sensors, instruments, machine parameters) to quantify (in real-time), uncertainty for machine diagnostics, prognostics and control inputs. It will also create a multiplexed high-accuracy two-photon dual-comb LiDAR 3D measurement system as an exemplar and traceable measurement solution. 

The second stage will create new, rapidly deployable mechatronic control models fusing multiphysics-based, predictive ML and large-language models to achieve evolutionary self-learning and polymorphic applications with inputs from all levels of embedded and post-process metrology, key challenge is how to control output quality, ML trust deficit, and lack of physics consistency. The raw data collections from activities conducted the first stage (as well as collected data from other Hub projects) will provide inputs for these models, allowing a fusion of modelled physics and physical data. Methods of stress-testing control models through adversarial and penetration testing techniques will be devised. 

The final part of this project will combine constrained generative design and topological optimisations to exploit the findings from the first two stages, resulting in a control architecture capable of assured self-calibration. Flexibility, reconfigurability, evolvability and robustness to different manufacturing requirements will be validated and complex time-varying multivariable interference will be created, for priority application within the Hub’s other sustainable manufacturing ‘strands’.
