Patent number: 10864613Abstract: Waterjet systems including control valves and associated devices, systems, and methods are disclosed. A waterjet system configured in accordance with a particular embodiment includes a fluid source, a jet outlet, and a fluid conveyance extending from the fluid source to the jet outlet. The system further includes a control valve positioned along the fluid conveyance downstream from the fluid source and upstream from the jet outlet. The fluid conveyance has a first portion upstream from the control valve and a second portion downstream from the control valve. The control valve is configured to controllably reduce a pressure of fluid within the second portion of the fluid conveyance relative to a pressure of fluid within the first portion of the fluid conveyance. The first portion of the fluid conveyance is configured to accommodate movement of the jet outlet relative to the fluid source.Type: GrantFiled: March 31, 2017Date of Patent: December 15, 2020Assignee: OMAX CorporationInventors: Chidambaram Raghavan, John H. Olsen, Douglas Kelley, Olivier L. Tremoulet, Jr., Andre Kashierski, Kevin A. Hay

Patent number: 7074112Abstract: The invention provides an apparatus that holds and tilts a tool over a tilt range and substantially about a vertex. The apparatus includes a base having pivots defining a base line and a base pivot distance. The apparatus also includes first and second pivot arms coupled to the base pivots, and a tool holder having pivots coupled to the first and second pivot arms. The tool holder pivots defining a tool holder line having a pivot distance different than the base pivot distance. The tool holder is arranged for holding the machine tool. An intersection of the base line and a selected pivot arm defines a control angle, such that changing the control angle changes a tilt of the tool holder with respect to the base line, and correspondingly tilts a longitudinal axis of the tool substantially about a vertex.Type: GrantFiled: March 21, 2003Date of Patent: July 11, 2006Assignee: Omax CorporationInventor: John H.

Patent number: 7035708Abstract: 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.Type: GrantFiled: May 9, 2005Date of Patent: April 25, 2006Assignee: OMAX CorporationInventor: John H.
