Integrity prediction of ground precision surfaces. This project aims to establish a new approach to enable a reliable and accurate prediction of precision surface grinding. Precision grinding is often the final step in the manufacturing chains for a broad range of metal, ceramic, optical glass and semiconductor components, which must have ultra-high surface integrity and accurate dimensions.

This project aims to establish a new approach to enable a reliable and accurate prediction of precision surface grinding. Precision grinding is often the final step in the manufacturing chains for a broad range of metal, ceramic, optical glass and semiconductor components, which must have ultra-high surface integrity and accurate dimensions. To date, the surface integrity of a ground component cannot be predicted due to the involvement of many random factors and variables in a precision surface grinding process, resulting in high failure rates and processes requiring repeated surface measurements. The novel approach for surface integrity prediction developed by this project will make a vital step forward in advancing the discipline of precision surfacing, establish a new knowledge base and bring about significant technological impacts to the manufacturing industry.Read moreRead less

Enhancing and modelling the abrasive waterjet impact and erosion process. This project aims to understand and improve the ultrahigh pressure abrasive waterjet (AWJ) impact process. The current AWJ machining technology transfers less than 20% of the jet energy to the workpiece, mainly due to the damping effect of a stagnant layer at the jet impact site. This project attempts to remove this effect using ultrasonic vibration and explore the new impact micromechanics under the coupled effect of part ....Enhancing and modelling the abrasive waterjet impact and erosion process.

Hard coatings are frequently applied to equipment operating in harsh environments. Often such coatings are highly brittle and so fragile under stress, especially at high temperatures or in corrosive environments. Premature failure can affect safety and lead to negative economic and environmental consequences. The objective of this project is to combine bioinspired microstructural design with an emerging alloying concept to produce a breakthrough in the development of engineering coatings; for example, overcoming the long standing trade-off between hardness and toughness. Such an innovative coating is expected to be highly durable in extreme conditions, and in so doing will help transform manufacturing, mining and desalination industries.Read moreRead less
