A method of machining includes mounting a component in a drilling machine. The component has a target region where the hole is to be drilled. The component and a jet head are situated relative to each other in a drilling arrangement in which the target region is at a first position that is vertically equal to or vertically above a second position at which the jet head is located. A liquid stream is jetted from the jet head and contains either abrasive particles or a laser beam. The stream impinges the target region, and the abrasive particles or the laser beam cause removal of material from the component to form the hole. The liquid stream rebounds off of the component as back-splash. The drilling arrangement causes gravitational draining of the back-splash from the target region to reduce interference between the back-splash and the liquid stream.

A cutting method by applying a particle beam of metallic glass onto a substrate to cut or partially cut the substrate with high production efficiency, low production cost and better environmental protection.

A waterjet system in accordance with at least some embodiments includes a carriage, a motion assembly configured to move the carriage horizontally relative to a workpiece, and a cutting head carried by the carriage. The waterjet system can also include a kinematic chain through which the cutting head is operably connected to the carriage. The kinematic chain can include first, second, and third joints rotatably adjustable about different first, second, and third axes, respectively. The carriage and the first and second joints can be configured to move the cutting head along a path relative to the workpiece while the cutting head directs a jet toward the workpiece to form a product. The third joint can be configured to shift a kinematic singularity away from the path to reduce or eliminate delay and corresponding reduced cutting accuracy associated with approaching the kinematic singularity.

An abrasive head with inserted jet for cleaning/removing material surfaces and splitting/cutting materials by a liquid beam enriched with solid abrasive particles to extend the tool lifetime by eliminating damage to the liquid jet's aperture by the abrasive, avoid degrading the abrasive inside the tool and increase the cutting power and flow efficiency.

A computer-implemented method is provided for shaping an edge of a part to be cut from a workpiece using a material processing system comprising a processing head configured to deliver a processing stream. The method includes calculating a start point and an end point of a shaping path proximate to the edge of the part based on a desired edge profile and determining a set of operating parameters to controllably impinge the processing stream about the edge of the part to execute the shaping path from the start point to the end point. The method further includes positioning the processing head normal to a surface of the part and controllably impinging the processing stream at the edge of the part, by the processing head, to shape the desired edge profile.

Embodiments presented provide for a slip wedge anchor system that is used in plugs for hydrocarbon recovery operations, wherein the plugs are made through a sacrificial tooling element.

The present disclosure discloses an abrasive water jet full-section cutting type cutter head and application devices. The cutter head includes a cutter head body and a rotor eccentrically arranged on a working surface of the cutter head body. The rotor revolves with the cutter head body and also rotates about its own axis. At least one first nozzle is arranged on an edge of a working surface of the rotor. At least one group of second nozzles and at least one third nozzle are arranged on the working surface of the cutter head body, and the second nozzles and the third nozzle cooperate during the rotation of the cutter head body and the rotor, then a material to be cut is cut into a plurality of concentric rings, and the first nozzle cuts off the ring material to form fragments.

High-pressure fluid jet systems are provided which include a pump to selectively provide a source of high-pressure fluid, a cutting head assembly configured to receive the high-pressure fluid and generate a high-pressure fluid jet for processing workpieces or work surfaces, and a fluid distribution system in fluid communication with the pump and the cutting head assembly to route the high-pressure fluid from the pump to the cutting head assembly. The pump, the cutting head assembly and/or the fluid distribution system include at least one fluid distribution component having a unitary body formed from an additive manufacturing or casting process with an internal passage having at least a curvilinear portion to efficiently route matter through the fluid jet system. Example fluid distribution components include fittings, valve bodies, cutting head bodies and nozzles of the high-pressure fluid jet systems.

A device for providing abrasive to a cutting head in a liquid jet cutting system can include an abrasive inlet configured to receive abrasive from an abrasive source, an abrasive outlet downstream from the abrasive inlet and configured to provide the abrasive to the cutting head, and a backflow diverter configured to discharge backflow from the device. In some embodiments, the backflow diverter can be configured to discharge a first portion of the backflow from the device, and device can further include one or more spillways configured to discharge a second portion of the backflow from the device. The one or more spillways can be positioned upstream from the backflow diverter and/or downstream from the abrasive inlet. The backflow diverter and/or the spillways can at least partially or fully prevent the backflow from flowing upstream through the abrasive inlet and/or into the abrasive source.

A system for moving a cutting device gantry or similar structure on a material processing machine can include a mounting structure configured to be operably coupled to the gantry and a drive assembly movably coupled to the mounting structure. The drive assembly can be configured to move the mounting structure and the gantry in a first direction relative to a gantry guide shaft of the material processing machine. The drive assembly can also be movable relative to the mounting structure in a second direction, perpendicular to the first direction. 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.
