Abstract：

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.
