  • As an advanced manufacturing technology with distinct advantages over the other technologies on various aspects, ultrahigh pressure abrasive waterjet (AWJ) has been increasingly used by industry for processing various materials. The research group at the University of New South Wales (UNSW) in Australia has been developing this technology and explore the associated sciences for over 20 years. A recently published bibliometric analysis of abrasive water jet machining research has identified the UNSW group as the most influential and active group in the world in this subject area. Since 2000, this group has been taking a new avenue to develop micro AWJ technologies to meet the need of industry in the fabrication of miniature structures with high-integrity surface quality. This effort is motivated by the fact that the materials used to construct miniature structures are often difficult-to-machine and many readily available technologies either cannot realise the necessary precision or are costly. As a result, damage-free fabrication of micro structures at commercially viable cost has been claimed as one of the most cutting-edge technologies in the 21st Century. This review summarises some of the work that has been undertaken at UNSW on the development of an AWJ micro-machining technology, focusing on the system design currently employed to generate a micro abrasive jet, the erosion mechanisms associated with the processing of some typical brittle materials of both single- and two-phases, and the processing models developed for mathematically and quantitatively estimating the process performance measures. The review concludes on the viability of the technology and the prevailing trend in its development.

Abstract: As an advanced manufacturing technology with distinct advantages over the other technologies on various aspects, ultrahigh pressure abrasive waterjet (AWJ) has been increasingly used by industry for processing various materials. The research group at the University of New South Wales (UNSW) in Australia has been developing this technology and explore the associated sciences for over 20 years. A recently published bibliometric analysis of abrasive water jet machining research has identified the UNSW group as the most influential and active group in the world in this subject area. Since 2000, this group has been taking a new avenue to develop micro AWJ technologies to meet the need of industry in the fabrication of miniature structures with high-integrity surface quality. This effort is motivated by the fact that the materials used to construct miniature structures are often difficult-to-machine and many readily available technologies either cannot realise the necessary precision or are costly. As a result, damage-free fabrication of micro structures at commercially viable cost has been claimed as one of the most cutting-edge technologies in the 21st Century. This review summarises some of the work that has been undertaken at UNSW on the development of an AWJ micro-machining technology, focusing on the system design currently employed to generate a micro abrasive jet, the erosion mechanisms associated with the processing of some typical brittle materials of both single- and two-phases, and the processing models developed for mathematically and quantitatively estimating the process performance measures. The review concludes on the viability of the technology and the prevailing trend in its development.
