Description | One interesting finding in the project is that the material removal in a polishing process is strongly affected by the abrasive grain size, shape and slurry chemical compounds. The mechanical removal mechanism at nanometre level presents similar features as at the micrometre level. New simulation and analyses convinced that chemical reactions plays an significant role in support polishing process. Through the modelling and simulation, the influence of abrasive grain size, shape and slurry chemical compounds can be quantitatively presented with some simple models, which could be used for the polishing real time control. Now we are going to integrate our models to the hydraulic models developed by our project partners in Huddersfield University. In the end of the project, we wish we could establish a applicable mathematical model that could be used in industrial applications. |
Exploitation Route | If the project could be extended to a longer period with more computing resources, the models could cover full scale as in wide range of industrial operation. |

Collaborator Contribution | with the project, a consortium has been set up to promote polishing research. Focusing on the collaboration in the consortium seeks to explore new multi-physics, multi-scale science at the interface between computational fluid dynamics and molecular dynamics, and then apply this to a practical manufacturing case with potentially high impact. In this regard, the proposal responds to 'market pull' for precision functional surfaces, especially optics, and including complex "freeform" surfaces that underpin many modern products, e.g. head-up and head-mounted displays, conformal optics, remote-sensing and advanced lighting. Extreme-precision optics are required for semiconductor EUV photolithography. Precise nonoptical surfaces are required, e.g. in healthcare (knee/hip implants) and for industrial moulds & dies for many products (e.g. moulded complex lenses for consumer products). Bespoke precision optics underpin much of the Science Base, from ground & space-based astronomy to synchrotron sources, high-power laser-systems, X-ray imaging and more, yet are costly and slow to procure. |
