Abstract: Abrasive waterjets (AWJ) were used for the first time to commercially singulate electronic chips such as those used for flash memory cards found in digital cameras, cell phones, and universal ...

Abstract: Ultrahigh-pressure abrasive-waterjets (AWJs) are being developed as net shape and near-net-shape machining tools for hard-to-machine materials. These tools offer significant advantages over existing ...

Abstract: The general characteristics of surfaces machined with abrasive-waterjets (AWJs) are discussed in terms of surface texture and surface integrity. Data are presented from several studies involving ...

Abstract: An experimental and theoretical investigation was conducted to study the cutting of ductile metals with high-velocity abrasive jets. The investigation involved experimental cutting tests, visualization ...

Abstract: Abrasive-waterjets (AWJs) are formed by mixing high-pressure (up to 400 MPa) waterjets (0.1 to 1 mm in diameter) with abrasive particles in mixing tubes with typical 1/d ratios of 50 to 100. ...

Abstract: The feasibility of using abrasive-waterjets (AWJs) for milling has been investigated in this research. The results of preliminary milling experiments indicate that abrasive-waterjets have great ...

Abstract: A study was undertaken to determine the feasibility of the AWJ process for controlled depth milling of gamma Titanium Aluminide tiles. It was demonstrated that milling can be accomplished to ...

Abstract: Waterjet technology development for 600-MPa (87-Ksi) operations involves efforts on machining process development, pumps, plumbing, nozzles, and machining systems development. In this paper, data ...

Abstract: Increasing the pressure of abrasive waterjet, while fixing the jet power, increases the jet’s power density and thus the cutting speed may increase. This was observed for steel, aluminum, and ...

Abstract: This paper presents a study on using high-pressure ammonia and abrasive ammonia jets for cutting and washout of chemical weapons. The work focused on chemical rocket M55 simulants. A test ...
