Abrasive jet machining (AJM) is a non-traditional manufacturing technology, in which the work material is removed by erosion due to the high velocity stream of abrasives and fluid. This technology includes a group of processes, such as abrasive waterjet machining, abrasive air jet micromachining. Owing to some advantages of the processes, such as thermal damage free, no tool wear, flexibility in machine setup, and the capability to work on almost any materials, there has been an increasing interest from industry on this technology. This presentation will introduce our recent research efforts on understanding the abrasive jet machining processes. It includes the exploration of the mechanics of material removal, characterisation and modelling of the abrasive jet and the particle velocities, micro-hole geometry evolution by using abrasive air-jet micromachining, abrasive waterjet machining of Inconel 718 and titanium alloy Ti-6Al-4V, etc. Existing research gaps will be discussed to seek potential research collaboration.


Dr Huaizhong Li is currently a Senior Lecturer at the School of Engineering and Built Environment, Griffith University, Australia. He obtained a B.E. degree from Tsinghua University, M.E. from Xi’an Jiaotong University, and Ph.D. from the National University of Singapore (NUS). He has extensive R&D experience in academia and industry. He had been a Senior Research Engineer at Singapore Institute of Manufacturing Technology (SIMTech) from 2001 to 2008, and an Associate Principal Engineer with Vestas Technology R&D Singapore from 2008 to 2010. Before joining Griffith University in 2014, he was a Lecturer at the School of Mechanical and Manufacturing Engineering, UNSW Australia, from 2011 to 2014. His research interests include advanced manufacturing technologies, micromachining, machine tool dynamics, vibration monitoring and control, and mechatronics. He is a recipient of the 2015 Thatcher Bros Prize by the Institution of Mechanical Engineers (IMechE), UK.
