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.

本计画旨在了解及改善超高压磨料水射流的冲击过程。目前的AWJ加工技术将不到20%的射流能量转移到工件上，这主要是由于射流冲击部位的停滞层的阻尼作用。本计画尝试利用超音波振动来消除此效应，并探讨粒子冲击与工件振动耦合作用下的新冲击细观力学。预期的结果是一种新的AWJ技术，用于高效，多尺度加工，并提高工业制造高完整性产品的能力。
