摘要： Disclosed herein are systems and methods for improving the performance of a fluid jet cutting system by testing and adjusting characteristics of the system based on the effect of the characteristics on forces imparted by the system to a workpiece being cut. Also disclosed are systems and methods for monitoring and validating the performance of fluid jet cutting systems, and for diagnosing such systems. In some cases, the technologies described herein can be used to determine whether components of a fluid jet system require maintenance, or that characteristics of the system require adjustment.

摘要： Fluid jet cutting systems, components and related methods for generating relatively low load abrasive fluid jets that are particularly well suited for cutting fragile, brittle or otherwise sensitive materials are provided. An example method includes supplying fluid at an operating pressure of at least 60,000 psi to an orifice having a circular cross-sectional profile with a diameter that is less than or equal to 0.010 inches to create a fluid jet that leaves a fluid jet cutting head through a jet passageway having a circular cross-sectional profile with a diameter that is less than or equal to 0.015 inches.

摘要： An abrasive slurry delivery system configured to discharge a high pressure mixture of water (30) and abrasives (54, 54′) for further admixture with a flow of high pressure water (30) to generate an abrasive slurry and ultimately an abrasive slurry jet is provided. The delivery system includes a storage chamber (56), a discharge chamber (58) and a shuttle chamber (60) positioned therebetween. The shuttle chamber (60) is configured to intermittently receive abrasives (54) from the storage chamber (56) and intermittently supply the abrasives (54, 54′) mixed with high pressure water (30) to the discharge chamber (58) to be selectively discharged therefrom. High pressure abrasive slurry cutting systems and related methods are also provided.

摘要： Disclosed herein are components, systems, and methods for performing a finishing operation on an article. Finishing operations include, but are not limited to removal of powder from a surface, improving surface finish, and peening. Embodiments of the disclosed components, systems, and methods include the use of waterjets to impact a surface of the article with an abrasive. Impacting the surface of the article with the abrasive alters a characteristic of the article without cutting through the portion of the article.

摘要： Fluid jet systems, components and related methods are provided which are well adapted for processing workpieces under particularly work-friendly conditions. Embodiments include fluid jet systems and related methods that reduce, minimize or eliminate a gap between a workpiece being processed and jet receiving devices that receive and dissipate the energy of a fluid jet passing through the workpiece. Other embodiments include fluid jet systems and related methods involving fluid jet processing of workpieces in a submerged condition. Still further embodiments include fluid jet systems and related methods involving position and orientation adjustment of a fluid jet receptacle to coordinate the path of an incoming fluid jet with a central axis or other feature of the fluid jet receptacle.

摘要： Computer based methods, systems, and techniques for planning and generating machining paths for a tool that manufactures a three dimensional object having beveled or “compound” contours from a workpiece. A computer aided design (CAD)/computer aided manufacturing (CAM) system creates intermediate machining path surfaces that extend based on a CAD solid model representing the geometry of the object to be manufactured. The intermediate machining path surfaces extend to a shape that simulates a cutting beam (e.g., a waterjet, a laser beam, etc.) of the tool. For a flat workpiece, the machining path surfaces may extend from a top surface of the workpiece, which is a tool beam entrance surface, to a bottom surface of the workpiece, which is a tool beam exit surface. An operator is able to visualize the cuts to be made and the actual finished object geometry, without requiring the creation of multiple CAD solid models.

摘要： A waterjet cutting head assembly is provided which includes an orifice unit to generate a high-pressure waterjet, a nozzle body and a nozzle component coupled to the nozzle body with the orifice unit positioned therebetween. The nozzle component may include a waterjet passage, at least one jet alteration passage and at least one environment control passage. The jet alteration passage may intersect with the waterjet passage to enable selective alteration of the waterjet during operation via the introduction of a secondary fluid or application of a vacuum. The environment control passage may include one or more downstream portions aligned relative to the fluid jet passage so that gas passed through the environment control passage during operation is directed to impinge on an exposed surface of a workpiece at or adjacent to a location where the waterjet is cutting the workpiece. Other high-pressure waterjet cutting systems, components and related methods are also provided.
