摘要： A method for dicing a die from a substrate for bonding that leverages laser and multiple etch processes. The method may include performing a laser cutting process to form a cut that removes a first portion of a dicing street in the substrate, performing a first plasma etch process to increase the laser kerf width to a first plasma etch width that is less than a dicing street width and to remove any non-silicon material from a bottom of the cut, and performing a second plasma etch process to increase the first plasma etch width to the dicing street width and to remove any remaining portion of the dicing street to completely separate the die from the substrate.

摘要： A method for producing a tray for storing aneurysm clips, in which a metal plate is equipped with perforations. The perforations are produced by laser cutting. The plate with the perforations is reshaped by bending to form a corrugated sheet or a sheet with trapezoidal corrugations. The sheet has at least one channel-like indentation for storing aneurysm clips. A tray for storing aneurysm clips includes a corrugated sheet or a sheet with trapezoidal corrugations equipped with laser-cut perforations. The corrugated sheet or sheet with trapezoidal corrugations has at least one channel-like indentation.

摘要： A plasma cutting system for measuring or monitoring the voltage between a plasma torch and the material being cut to determine a voltage or voltage signature and comparing that measurement against predetermined values to indicate that an initial pierce of the material is complete, and based on the measurement, moving the torch or the material to a different location for additional cutting. The system further provides a Fix Drawing Tool, which will automatically detect and fix gaps or overlaps in a drawing that are very difficult to find visually. These gaps and overlaps become a problem when trying to make a proper toolpath because a CAM program requires a clean, closed shape. The system also provides a Dynamic Corner Looping system, which automatically adjusts with the feed-rate and accelerations of the toolpath and plasma machine, eliminates unwanted dross, sharpens corners and minimizes material loss. A pendant tethering system is also disclosed for managing control of a CNC machine remotely. Additional disclosed functionality includes a data collection system, a manual hand wheel with 3D simulation and a multiple fabrication head management system.

摘要： A meshing structure for plate welding, and a tack-free welding device and method are provided. The device comprises a connecting frame, a welding gun, and a cutting mechanism, the welding gun is fixed on the connecting frame, and the cutting mechanism is connected to the connecting frame. The meshing structures are disposed on welded plates, and after being assembled, the two plates can be restrained by the meshing structures in multiple dimensions. Before welding, edges of the plates are cut according to the form of the meshing structures, then the plates are assembled and meshed; after the position of the welding gun is adjusted, the cutting mechanism and the welding gun are driven by a welding robot or a special welding machine to move along a weld; and the meshing structures are removed by the cutting mechanism, and then normal welding is performed by the welding gun.

摘要： Disclosed herein is a film cutting system for dividing and forming a film sheet having a predetermined unit width and unit length from a raw film by laser cutting of the raw film. The film cutting system includes: a supply unit configured to intermittently supply the raw film by a predetermined unit supply length in a length direction of the raw film; a first laser unit including first and second laser nozzles each configured to radiate a laser beam onto the raw film, and a first head driver configured to convey the first laser nozzle and the second laser nozzle in a width direction of the raw film perpendicular to the length direction in a reciprocating manner; and a second laser unit including a laser nozzle disposed spaced apart from the first laser unit by the unit length in the length direction and configured to radiate a laser beam onto the raw film, and a second head driver configured to convey the laser nozzle in the width direction in a reciprocating manner, wherein, when the raw film is supplied by the supply unit, the first head driver dispose the first laser nozzle and the second laser nozzle so as to be spaced apart from each other by the unit width, and each of the first laser nozzle and the second laser nozzle radiates, in the length direction, the laser beam onto the raw film supplied by the supply unit to slit the raw film, and wherein, when the slitting of the raw film is completed, the supply unit stops supplying the raw film; the first head driver conveys one of the first laser nozzle and the second laser nozzle in the width direction; the second head driver conveys the laser nozzle in the width direction; and the one of the first laser nozzle and the second laser nozzle and the laser nozzle respectively radiate the laser beam onto the raw film in the width direction to cut the raw film to divide and form the film sheet from the raw film.

摘要： A moveable head of a computer numerically controlled machine may deliver electromagnetic energy sufficient to cause a first change in a material at least partially contained within an interior space of the CNC machine. A feature of the material may be imaged using at least one camera present inside the interior space to update a position of the material, and the moveable head may be aligned to deliver electromagnetic energy sufficient to cause a second change in the material such that the second change is positioned on the material consistent with the first change and with an intended final appearance of the material. Methods, systems, and article of manufacture are described.
