Abstract
A flash vaporizing liquid jet cutting tool and method for piercing with minimal damage to the cut material. The liquid is preferably superheated water, typically with abrasive particles added after the jet is expressed through a nozzle (abrasive water jet, AWJ) or with abrasive particles added before the jet is expressed through a nozzle (abrasive slurry jet, ASJ). In piercing, only a portion of water that has not changed phase enters into the cavity or must leave the cavity and the piercing pressure, which can damage the material, is therefore reduced.
