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.

该项目旨在了解和改进超高压磨料水射流 (AWJ) 冲击工艺 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处停滞层的阻尼作用。该项目试图利用超声波振动消除这种影响，并探索粒子冲击和工件振动耦合作用下的新冲击微观力学，预期成果是一种新的 AWJ 技术，可实现高效、多尺度加工，并提高工业制造高完整性产品的能力。
