摘要： Particle-delivery devices, abrasive jet systems, and associated devices, systems, and methods are disclosed herein. In certain aspects, the particle-delivery devices can include an elongated fluidizing chamber and a metering assembly. The metering assembly can include a particle flow path extending from the fluidizing chamber. The metering assembly can also include a carrier-gas passage extending to an injection orifice proximate the fluidizing chamber. The metering assembly can be configured to inject carrier gas into the fluidizing chamber to fluidize particles within the fluidizing chamber. Fluidizing the particles at different carrier-gas pressures and/or flow rates can change the rate of particle delivery. For example, the metering assembly can include a metering opening and a regulator configured to change a steady-state pressure and/or flow rate of carrier gas entering the fluidizing chamber. Systems disclosed herein can include a controller configured to change a flow rate of particles through the metering opening.

摘要： Various embodiments of abrasive jet systems are described herein. In one embodiment, an abrasive jet system includes an abrasive container and a nozzle assembly. The nozzle assembly has a mixing region or cavity and an abrasive inlet. The abrasive jet system can also include an abrasive supply conduit that is operably coupleable between the abrasive container and the abrasive inlet. The abrasive supply conduit includes a first interior surface portion configured to be positioned proximate to the abrasive inlet and a second interior surface portion, different from the first interior surface portion, configured to be spaced apart from the abrasive inlet. In one aspect of this embodiment, the first interior surface portion has a greater ability to repel fluid (e.g., water) than the second interior surface portion, thereby reducing a tendency of the abrasives to clog the abrasive supply conduit.

摘要： A computerized method for determining a tilt parameter of a cutting head of a fluid-jet apparatus. The method includes receiving a target-piece shape, describing an ordered path defining the target-piece shape, and segmenting the path into small straight lines of approximately equal length. The method further includes determining a cutting-head translation speed for each of the small straight lines, determining a tilt parameter of the cutting head with respect to the plane of the workpiece in response to the speed and a fluid jet-shape parameter for each of the small straight lines, storing the small straight lines and the determined tilt parameter associated with each small straight line in a memory, and sending the stored data to the fluid-jet apparatus. The method may include controlling the tilt of the cutting head in accordance with the tilt parameter for each small straight line as the cutting head cuts the workpiece.

摘要： A high-pressure liquid jet cutting system can include a hopper configured to contain an abrasive mixture that includes abrasive and an additive, and a cutting head configured to receive the abrasive mixture from the hopper and introduce the abrasive mixture into a high-pressure liquid jet. The system can further include a sensor configured to detect a characteristic of the abrasive mixture associated with the additive, and one or more processors operably connected to the sensor and configured to determine information about the abrasive based, at least in part, on the detected characteristic. The one or more processors can be configured to adjust or otherwise control operation of one or more components of the high-pressure liquid jet cutting system based, at least in part, on the information to, e.g., improve or optimize system performance.

In some embodiments, the system includes one or more guide wheels rotatably coupled to the mounting structure. Each of the guide wheels can include an annular outer portion having curvature configured to complimentarily engage the gantry guide shaft. The annular outer portion can be resiliently deformable and configured to conform to the gantry guide shaft during movement of thereon.

摘要： A waterjet system in accordance with at least one embodiment of the present technology includes a cutting head and an associated catcher assembly. The cutting head directs an abrasive-containing waterjet toward a workpiece supported by a cutting deck of the catcher assembly. The catcher assembly also includes a tank and a container fluidly connected to the tank. The tank contains abrasive-containing liquid in which the waterjet diffuses after the waterjet passes through the workpiece. The container collects abrasive at least primarily by shielding abrasive-containing liquid within the container from at least some turbulence of abrasive-containing liquid within the tank during operation of the waterjet system. The catcher assembly also includes a quick-release coupling through which the container is removably connected to the cutting deck. Operating the quick-release coupling allows the container to be removed to dispose of the collected abrasive.

摘要： The present disclosure relates to abrasive material delivery systems for liquid jet cutting systems. The abrasive material delivery systems can include a valve configured to adjust an inflow of abrasive material into the abrasive material delivery system from a source of abrasive material. The systems can include a chamber downstream of the valve and configured to receive the inflow of abrasive material from the valve. The systems can include a metering component configured to control an outflow of abrasive from the chamber to a cutting head of the liquid jet cutting system. In some embodiments, the systems include a sensor configured to monitor movement of a top surface of a portion of abrasive material within the chamber as the top surface moves through the chamber; and a processing device operably connected to the sensor and configured to determine an abrasive flow rate through the metering component based on a speed of the top surface as monitored by the sensor.
