A comprehensive review of all the related investigations carried on water jet cutting or AWJ (AWJ) cutting is performed. The experimental methods and results used on this subject were examined, defined and compared by the researchers. This research shows that further improvements are possible in the water jet cutting method. In order to reduce the high cost of the empirical technique and increase the time efficiency, it is important to perform computerized Finite Element Analysis (FEA) or Computational Fluid Dynamics (CFD) based AWJ processing. An attempt has been performed to systematically arranged the research investigations conducted on water jet cutting. The studies on the definition of the nozzle failure, calculate using CFD of water jet cutting or AWJ cutting processes, the studies on the parameters influencing water jet cutting are reviewed and the future work for the further improvement of water jet cutting process is highlighted.

Mine waterjet cutting machine is mainly used for cutting steel strands in coal mines, and can also be used for cutting anchor rods and clearing rescue channels, etc. It has no cutting sparks, no thermal deformation, smooth and intact cuts, no pollution and sufficient abrasive sources, and is complementary to other cutting technologies. The system adopts premixed abrasive water-jet cutting technology, with the working pressure of 40 MPa, mass fraction of garnet of 20%, and target distance of 3~5 mm. With the case of Φ21.8 mm steel strand, its cutting speed is 45 mm/min and feedrate is 30 m/min. Under the assumed conditions, the pressure change model shows that, to ensure the cutting quality, steel strands should be cut only after the system pressure rises to close to the working pressure after about 100 s. After the system stops operation, its pressure needs to be reduced from the working pressure to the ambient pressure after 23 s.
