Disclosed herein are components, systems, and methods of operating an abrasive fluid jet system that recycles and reuses abrasive particles. The systems and methods described enable accurate metering and consistent feeding of wet abrasive particles thereby reducing the time and cost of operations associated with drying the recycled abrasive particles prior to reuse. The system may adjust a ratio of wet abrasive to dry abrasive being provided to a cutting head to form an abrasive fluid jet. Components of the system may overcome challenges associated with clumping and other issues that result in difficulty metering wet abrasive.

Systems and apparatus for use of wet recycled abrasive and methods of operation of said systems and apparatus

Systems and methods for providing real-time modification of cutting process programs using feedback from one or more sensors which measure one or more operational parameters of a cutting process and/or cutting apparatus. The sensor readings may be used to provide real-time modification of a motion program after such motion program has been provided to a motion controller. Examples of such operational parameters may include waterjet pump supply pressure, the abrasive mass flow rate, the force of the waterjet on the target piece, etc. The systems and methods discussed herein also utilize a cutting algorithm or program to calculate actual cut quality based on one or more sensor inputs, and to generate warnings or system shut-downs accordingly. The systems and methods discussed herein also utilize inspection devices to inspect coupons or first articles, and use the inspection data to autonomously modify motion programs and/or cutting process models without user intervention.

Autonomous modification of waterjet cutting systems

Reinforced diamond nozzles and methods of making the same for fluid jet cutting applications are provided. An example method includes forming or providing a tubular diamond body having a jet passage extending therethrough and establishing a protective casing around the tubular diamond body so that an entirety or substantially an entirety of an outer circumferential surface area of the tubular diamond body is directly contacted and reinforced by the protective casing. Establishing the protective casing around the tubular diamond body may include thermal spraying, casting, direct metal laser sintering, or other fabrication techniques.
