Optimization of Abrasive Waterjet Machining Process Parameters on Aluminium AL-6061

Abrasive Waterjet Machining (AGWM) is an emerging machining technology alternative for hard material parts, which are extremely difficult-to-machine by conventional machining processes. A narrow stream of high velocity water mixed with friction particles provides a relatively inexpensive and environmentally friendly production with a very high content removal rate. Because of that abrasive waterjet machining, has become one of the leading manufacturing technologies in a relatively short time. This letter reviews the research work from the beginning to the development of AWJM in the beginning of the last decade. It reports related to AWJM processes to optimize process variables, improve performance measures, monitoring and control of the process. A wide range of AZJM industrial applications for various class items are reported with variations. In this paper, the future trend of research work in the same area has also been discussed and found that Transverse Rate has a greater influence on the surface Roughness followed by Standoff Distance. Pressure had the least influence on Roughness. Pressure is the most significant parameter for Material Removal Rate, followed by Transverse rate and Standoff Distance respectively.
