Water-jet cutting is a nonconventional machining method that makes use of high-pressure water jets with (i.e., abrasive water-jet cutting) or without (i.e., plain water-jet cutting) fine abrasive particles to virtually cut any kind of materials into two- or three-dimensional shapes, provided that the machine has the capability of ultrahigh-pressure pump (UHP) and the flexibility of positional movement.
Theory and Application
Abrasive water-jet (AWJ) machining is considered to be a fast-growing nonconventional technology capable of processing any material regardless of its properties. Modern AWJ machining systems make use of high-pressure water jets (up to 6,200 bar) forced through a tiny orifice (0.1–0.3 mm) that enables the entrainment and acceleration of abrasive particles (e.g., garnet, Al2O3) to high velocities (200–800 m/s).
