A method for determining a spatial position of a liquid jet, in particular of a liquid jet for optically guiding a laser beam, comprises the steps: providing a collision object having a measuring point for interacting with the liquid jet, detecting a state of the liquid jet in a first configuration between collision object and liquid jet, changing the configuration so that the state of the liquid jet changes, detecting the configuration change between the first and second configuration.

Machine for recycling tyres by recovering the tyre tread rubber using waterjets. The machine comprises a loading unit for loading a tread, a processing unit, the processing unit comprising a framework comprising a preprocessing zone, a processing zone and a postprocessing design. The preprocessing zone drives a cut tread towards the processing zone. The processing zone comprises a processing module designed to direct a waterjet onto the recovered tread. The preprocessing zone comprises motorized guide rollers and presence sensors arranged in such a way as to allow a second tread to catch up with a first tread in such a way as to reduce, to the point of closing up, the space between two treads.

A cutting system includes a material removal tool having a fluid nozzle with an adjustable diameter, a workpiece including a target shape for removal, and a controller operable to adjust the diameter of the nozzle to vary fluid flow and control an amount of material removed by the material removal tool. The controller is adapted to adjust the nozzle to vary the fluid flow based on a position of the nozzle and workpiece data preoperatively obtained from the workpiece via a continuous feedback loop. A method of cutting a bone is also provided.

Disclosed herein are components, systems, and methods to improve performance and maintenance of high-pressure fluid systems, such as waterjet cutting systems.

Provided is: a method of manufacturing plate-like members and an intermediate body for plate-like members whereby the occurrence of shape defects in the plate-like members can be prevented; and a plate-like member in which shape defects are prevented. The method includes the steps of: providing a first breaking groove 12a in a first principal surface of a base material for plate-like members, the base material having the first principal surface and a second principal surface opposed to each other, and then providing a second breaking groove 13a in the second principal surface of the base material in a direction crossing the first breaking groove 12a in plan view to form an intermediate body 11 for wavelength conversion members (plate-like members); and breaking the intermediate body 11 for wavelength conversion members into separate parts along one of the first breaking groove 12a and the second breaking groove 13a and then breaking the intermediate body 11 for wavelength conversion members into separate parts along the other breaking groove, wherein in breaking the intermediate body 11 for wavelength conversion members into separate parts along the first breaking groove 12a, the intermediate body 11 is broken into separate parts along the first breaking groove 12a by pressing the intermediate body 11 from the second principal surface 11b side, and in breaking the intermediate body 11 for wavelength conversion members into separate parts along the second breaking groove 13a, the intermediate body 11 is broken into separate parts along the second breaking groove 13a by pressing the intermediate body 11 from the first principal surface 11a side.

A method and a waterjet machine for removing or stripping a ceramic coating from a substrate, especially from a metallic coating onto the substrate, using a pure waterjet without any additions. The method includes providing a water source and a nozzle for ejecting a jet of pure water onto the surface of a coated substrate; providing a substrate coated at least with a ceramic coating; positioning the nozzle and the substrate to one other such that a machining angle can be determined between the waterjet and the surface of the coated substrate at the location of impingement of the water jet onto the local coating surface; ejecting a pure waterjet by the nozzle impinging the ceramic coating for removing essentially or completely the ceramic coating from the substrate or from the metallic coating.

Vascular treatment devices and methods include a woven structure including a plurality of bulbs that may be self-expanding, a hypotube, for example including interspersed patterns of longitudinally spaced rows of kerfs, and a bonding zone between the woven structure and the hypotube. The woven structure may include patterns of radiopaque filaments measureable under x-ray. Structures may be heat treated to include various shapes at different temperatures. The woven structure may be deployable to implant in a vessel. A catheter may include a hypotube including interspersed patterns of longitudinally spaced rows of kerfs and optionally a balloon. Laser cutting systems may include fluid flow systems.

Methods of trimming fiber reinforced polymer composite workpieces are provided which use a pure waterjet discharged from a cutting head in liquid phase unladened with solid particles at an operating pressure of at least 60,000 psi and in combination with other cutting parameters to provide a final component profile without delamination, splintering, fraying or unacceptable fiber pullout or fiber fracture.

In some aspects, material processing head can include a body; an antenna disposed within the body; a first tag, associated with a first consumable component, disposed within a flux communication zone of the body at a first distance from the antenna, the first tag having a first resonant frequency; and a second tag, associated with a second consumable component, disposed within the flux communication zone of the body at a second distance from the antenna, the second tag having a second resonant frequency that is different than the first resonant frequency, where the first and second resonant frequencies are tuned based upon at least one of: i) a difference between the first distance and the second distance; or ii) a characteristic (e.g., shape) of the flux communication zone in which the first tag and/or the second tag is disposed.

Disclosed herein is an apparatus for removing material from a surface of a carrier. The apparatus comprises a buckling mechanism that comprises a gripper configured to engage the material. When engaged with the material, the gripper is movable relative to the surface of the carrier to move the material relative to the surface of the carrier and to form a buckle in the material. The apparatus also comprises a separation mechanism that is coupled to the buckling mechanism and comprises a wedge that is movable relative to the surface of the carrier to be insertable into the buckle formed in the material.
