An abrasive waterjet system in accordance with an embodiment of the present technology includes a cutting head, a catcher downstream from the cutting head, and a conveyance configured to carry slurry including abrasive material and liquid collected from the catcher toward the cutting head. The cutting head includes a jet-forming orifice and a mixing chamber downstream from the jet-forming orifice. The cutting head also includes a slurry inlet through which the mixing chamber receives slurry including abrasive material and liquid collected from the catcher. The abrasive waterjet system can be configured for substantially closed-loop recycling of wet abrasive material. This can be useful, for example, to increase abrasive material utilization efficiency and to decrease abrasive material disposal costs. These and/or other benefits may be realized both in the context of low pressure abrasive waterjet systems and in the context of high pressure abrasive waterjet systems.

A method for producing an optical coupling element made of elastomer includes filling a free-flowing elastomer formulation or its constituents into a mold so as to produce a flat sheet whose thickness is adapted to a thickness of the optical coupling element that is to be produced. The elastomer formulation or its constituents is cured to form an inherently stable elastomer. Individual optical coupling elements are cut out of the flat sheet.

A method for producing a diffusion cooling hole extending between a wall having a first wall surface and a second wall surface includes forming a cooling hole inlet at the first wall surface, forming a cooling hole outlet at the second wall surface, forming a metering section downstream from the inlet and forming a multi-lobed diffusing section between the metering section and the outlet. The inlet, outlet, metering section and multi-lobed diffusing section are formed by laser drilling, particle beam machining, fluid jet guided laser machining, mechanical machining, masking and combinations thereof.

The invention features methods and apparatuses for altering a cutting operation during operation of the pressurized liquid jet cutting system. A pressurized liquid jet cutting system includes a pressurized fluid jet cutting head having a plurality of components. The cutting head further includes a sensor configured to sense an operating condition. The sensor transmits a value of the operating condition to a computing device, which alters a subsequent cutting operation. Further, the fluid jet cutting head is configured to work with a data storage mechanism and a reader, such that the data storage mechanism in contact with a body of the fluid jet cutting head is configured to communicate information to a reader of the pressurized liquid jet cutting system. The information is usable to determine a condition of replacement (e.g., a remaining usable life) of the replaceable component, change an operating pressure, change a cutting speed, or alter another operating parameter of the pressurized liquid jet cutting system.

The flow inlet may be oriented to direct the cut food product into the at least one drum at a right angle to a longitudinal axis of the at least one drum. The at least one drum may be a plurality of drums including a first drum having the flow inlet and a second drum having the flow outlet. The system may include a passageway providing fluid communication from the first drum to the second drum. The passageway may include a tapered section. The flow inlet may be aligned with the flow outlet.

Systems and methods suitable for shaping and cutting materials. Such a system includes first and second carriage units that are independently operable to travel in a travel direction parallel to a longitudinal axis of a table supporting the material. The first and second carriage units have first and second arms, respectively. A cutting device coupled to the first arm forms a slit in the material, and a deburring device coupled to the second arm forcibly removes burrs from the slit. The deburring device is behind the cutting device relative to the travel direction and forcibly removes burrs in the travel direction toward a breakthrough point of the slit. The second carriage unit oscillates parallel to the travel direction so that the deburring device moves toward and away from the breakthrough point of the slit to remove burrs at the breakthrough point.
