Abstract
A waterjet cutting method is provided which includes directing a waterjet onto a surface of a workpiece that is exposed to the surrounding atmosphere, the interaction of the waterjet with the exposed surface defining a cutting location, and simultaneously directing a gas stream onto the exposed surface of the workpiece at or adjacent the cutting location to maintain a cutting environment at the cutting location that is, apart from the waterjet, substantially devoid of fluid or particulate matter. The method may further include moving a source of the waterjet relative to the workpiece to cut the workpiece along a desired path while continuously directing the gas stream onto the exposed surface of the workpiece at or adjacent the cutting location.
