摘要： A waterjet cutting method is provided which includes directing a waterjet onto a surface of a workpiece that is exposed to the surrounding atmosphere, the interaction of the waterjet with the exposed surface defining a cutting location, and simultaneously directing a gas stream onto the exposed surface of the workpiece at or adjacent the cutting location to maintain a cutting environment at the cutting location that is, apart from the waterjet, substantially devoid of fluid or particulate matter. The method may further include moving a source of the waterjet relative to the workpiece to cut the workpiece along a desired path while continuously directing the gas stream onto the exposed surface of the workpiece at or adjacent the cutting location.

摘要： A relief valve assembly is provided for use in connection with high pressure and ultrahigh pressure pumps. The relief valve assembly includes a valve pin having an engagement portion with a tapered surface and a valve seat having a valve pin receiving aperture defining a tapered surface on the valve seat to sealingly mate with the engagement portion of the valve pin when the valve pin is seated against the valve seat in a seated configuration. The valve seat further includes at least one bypass passage that extends from the valve pin receiving aperture to an exterior surface of the valve seat such that when the valve pin is displaced away from the seated configuration fluid can pass through the bypass passage and an annular space created between the engagement portion of the valve pin and the valve seat. Systems incorporating the relief valve assembly are also provided.

摘要： Land cultivating systems and methods utilizing high-pressure fluid jet cutting techniques are disclosed. An example system includes a mobile unit, a traveler arrangement operably coupled to the mobile unit to ride on the surface of stubble residues as the mobile unit moves across land to be cultivated, and a fluid jet cutting head supported by the traveler arrangement. The cutting head is configured to selectively discharge a high-pressure fluid jet to make a cut through the stubble residues and underlying soil as the mobile unit moves across the land. A soil opening device is provided to form a furrow in the ground in line with the cut made by the high-pressure fluid jet, and a liquid injector nozzle is provided to discharge fertilizer or other chemical(s) into the soil.

摘要： Systems and related methods are provided for maintaining a spatial relationship between a tool of the multi-axis machine (e.g., fluid jet nozzle of a fluid jet cutting machine) and a workpiece to be processed by the tool. An example system includes a contour follower apparatus having a sensor and a gimbal assembly operable with the sensor to sense a deviation between a machine focal point and a gimbal assembly focal point defined by the gimbal assembly as the gimbal assembly rides upon the surface of the workpiece during operation. The system may further include a gimbal mount assembly configured to sense a collision event of the gimbal assembly with another object.

摘要： A processing apparatus is provided to process a workpiece. The processing apparatus can have a low-profile nozzle system capable of navigating through spaces in order to process target regions with relatively small clearances. A fluid jet outputted from the nozzle system is used to cut, mill, or otherwise process the target region of the workpiece.

摘要： An apparatus for generating and manipulating a high-pressure fluid jet includes an end effector assembly coupled to a manipulator that imparts motion to the end effector along one or more axes. The end effector assembly includes a cutting head coupled to a source of high-pressure fluid and to a source of abrasive, to generate a high-pressure abrasive fluid jet. A motion assembly is coupled to the cutting head via a clamp positioned around the cutting head. A nozzle body assembly is removably coupled to the cutting head assembly upstream of the orifice. The nozzle body assembly may be separated from the cutting head assembly to allow access to the orifice, without removing the cutting head assembly from the clamp. The clamp has a quick release mechanism, allowing an operator to open the clamp by hand to allow access to the cutting head, and an alignment member is provided on an inner surface of the clamp to accurately locate the cutting head in the clamp. The motion assembly includes two motors coupled together to form a gimbal wrist, each motor having a horizontal axis of rotation. The two axes of rotation are perpendicular to each other, but are not necessarily aligned with the manipulator's axes of motion. Spray from the abrasive fluid jet is contained by a shield provided directly in an end region of the cutting head assembly.
摘要翻译：用于产生和操纵高压流体射流的装置包括联接到操纵器的端部执行器组件，该操纵器沿着一个或多个轴向末端执行器施加运动。端部执行器组件包括联接到高压流体源和研磨源的切割头，以产生高压磨料流体射流。运动组件通过位于切割头周围的夹具联接到切割头。喷嘴主体组件可拆卸地联接到在孔口上游的切割头组件。喷嘴主体组件可以与切割头组件分离，以允许进入孔口，而不从夹具移除切割头组件。夹具具有快速释放机构，允许操作者用手打开夹具以允许进入切割头，并且在夹具的内表面上设置对准构件以将切割头精确地定位在夹具中。运动组件包括耦合在一起以形成万向手腕的两个马达，每个马达具有水平的旋转轴线。两个旋转轴线彼此垂直，但不一定与机械手的运动轴对齐。从磨料流体射流喷射由直接设置在切割头组件的端部区域中的屏蔽物容纳。
