The Use of an Abrasive Waterjet System at 700 Bar for the Cutting of Military Munitions as Part of a Demilitarization Program
نویسندگان
چکیده
The use of abrasive waterjets for cutting into munitions of varying types as part of the decommissioning process is becoming more common. The performance of one such system, operated at 700 bar is discussed, from the aspect of cutting performance in sectioning 40 mm shells. The amount of sparking generated, and the thermal buildup of heat on the inner wall of the munition is discussed, as part of the evaluation of process risk. An apparatus to remotely cut shells is described, and its performance with different grit types and sizes evaluated.

متن کاملSurface Texture in Abrasive Waterjet Cutting
When cutting thick material with an abrasive wateriet, the surface area can be characterized by two texture types. At the top of the cut, the surface texture is smooth. At the bottom, the slurry jet exiting the workpiece forms large striations in the surface. An investigation was conducted to experimentafly determine the influence of the abrasive waterjet cutting parameters on surface texture. ...
