  • Publication number: 20230330812
    Abstract: 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.

  • Publication number: 20230136030
    Abstract: Disclosed herein are components, systems, and methods of operating an abrasive fluid jet system that recycles and reuses abrasive particles for multiple cycles. The systems and methods include adjusting one or more operating parameters of the abrasive fluid jet system to compensate for a reduction in cutting power of the used abrasives as the used abrasive particles are continuously discharged from the outlet of the cutting head across multiple cycles. The one or more operating parameters include fluid pressure that forms the fluid jet, a cutting speed of the cutting head, and flow rate of abrasive particles, which are changeable while continuing to operate the abrasive fluid jet system. The one or more operating parameters include an orifice size through which a fluid passes to generate the second fluid jet, a mixing tube diameter through which the second abrasive fluid jet passes, and a length of the mixing tube.

  • Patent number: 8651920
    Abstract: A waterjet system for generating and delivering fluid jets suitable for processing a workpiece has a cutting head body and a mixing tube. The cutting head body includes a mixing chamber and a bore. The bore is positioned downstream of the mixing chamber, and an abrasive fluid jet from the mixing chamber passes through the mixing tube. The mixing tube has a first coupler adapted to magnetically couple the mixing tube to the cutting head body when the mixing tube is installed. The cutting head body has a second coupler positioned to engage the first coupler of the mixing tube to keep the mixing tube properly positioned during operation of the waterjet system.

  • Patent number: 8308525
    Abstract: A waterjet system selectively produces fluid jets for water jet cutting or abrasive jets for abrasive-waterjet-cutting. The abrasive materials in the abrasive jet are determined based on the properties of the workpiece. The waterjet system includes an abrasive delivery system that is capable of delivering either a single abrasive or a plurality of abrasives as an abrasive blend, to a cutting head assembly. The cutting head assembly entrains the abrasive into a fluid jet to form an abrasive jet.

  • Patent number: 8210908
    Abstract: An abrasive waterjet assembly has a cutting head assembly with a venting system for controlling the flow of abrasive within a cutting head body. The venting system includes one or more vents for regulating the pressure within a cutting head body to minimize, limit, or substantially eliminate any abrasive from reaching a jewel orifice. The vents include venting ports positioned between an orifice mount that retains the jewel orifice and a mixing region in which abrasive is mixed with a fluid jet produced by the jewel orifice. An isolator retained in the cutting head body further inhibits the upstream flow of abrasive, if any.
