Methods of ultrasonic drilling may be used to form perforated sheets by forming holes through a workpiece using a needle or needle array operatively coupled to an ultrasonic actuator. The needle is brought to repeatedly contact the surface of the workpiece at an ultrasonic operating frequency, thereby forming the hole through the workpiece. Such steps are repeated to form a plurality of holes in the workpiece, thereby forming a perforated sheet which may be used in an acoustic liner for noise attenuation. The workpiece may be heated while the holes are formed, via a remote heating unit that locally heats a portion of the workpiece.

The present disclosure relates to the technical field of cutting machining, and discloses a cross-scale structure feature surface machining method based on a multi-component collaborative vibration. A vibration in a z-axis direction is applied to a servo movement mechanism to realize the cutting of a micron-scale structure and the adjustment of the cutting depth; and the vibration in the z-axis direction is applied to a three-axis movement platform to realize the cutting of a millimeter-scale structure and the adjustment of the cutting depth. A required cross-scale structure feature surface can be machined and formed at one time through a collaborative vibration among a vibrating tool, a servo movement mechanism, and/or a three-axis movement platform according to the structure type contained in the required cross-scale structure, which can simplify a process flow and improve the machining efficiency, and has high economic efficiency.

The control module is configured to control the laser to laser braze or laser weld two parts; and control ultrasonic vibration of the first cutting tip to remove one or more layers from at least one of the two parts prior to or subsequent to the laser brazing or laser welding of the two parts.

An electrode assembly manufacturing apparatus includes an electrode sheet supply unit for supplying an electrode sheet on which electrode mixture coating and non-coating portions are formed, a cutting unit at the rear of the supply unit for forming an electrode tab at the electrode sheet, and a lamination unit at the rear of the supply unit and configured to laminate positive and negative electrodes stacked with a separator between them. A cutting unit die supports the electrode sheet and an ultrasonic cutter spaced from the die forms the tab. A cutting line of a cutting edge of the cutter corresponds to a periphery of a unit electrode in a tab forming direction. The cutting and lamination units are on the same line in a continuous process to reduce a necessary space for electrode assembly manufacture and prevent electrode sheet foil deformation and electrode mixture layer damage in the cut section.

An ultrasonic weld/seal-cut system having an ultrasonic cut stack assembly, including an ultrasonic cutting horn with a transducer arranged to impart an ultrasonic energy to the ultrasonic cutting horn (sonotrode) and allow for wider cutting applications while minimizing deflections of the cutting horn under force.
