Abrasive waterjet cutting is essentially a cold cutting process. The work piece are not heat-stressed or no structural changes are induced that can adversely affect metallurgic properties in materials being cut.

Waterjet Cutting Methodology
Most abrasive waterjet cutting theories explain abrasive waterjet cutting as a form of accelerated micro erosion. High pressure water at 3800 bar is passed thru a tiny orifice at a speed of approx.900 m/s – nearly three
times the speed of sound. The result is a coherent very thin extremely high velocity waterjet with a diameter of approx. 0.08 to 0.50 mm. Natural garnet sand particles are made to be sucked into the stream of the coherent waterjet and directed to hit the work piece on the cutting line with the very high velocity. There by hardest of metals and non metals can be cut or machined by micro erosion. Automating the process with programmable systems in conjunction with the CNC control provides precision and high flexibility with a wide variety of part profiles.
Thus, Abrasive jet cutting systems are considered as an efficient tool to cut work pieces which are previously considered "unmachineable" by conventional cutting methods.
