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. 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 particle impact and workpiece vibration. The expected outcome is a new AWJ technology for efficient, multi-scale machining, and to increase industry’s capability in fabricating high-integrity products.Read moreRead less

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
