摘要:
A method for stripping ceramic from a component includes applying a liquid to a ceramic coating of an outer surface of the component. The method also includes directing a plurality of laser pulses at the ceramic coating with the applied liquid in order to spall the ceramic coating from the component.

A reflected beam detector detects a reflected beam reflected from a sheet metal when the sheet metal is irradiated with a laser beam so that the sheet metal is cut. A processing state determination unit is provided with a standard deviation value calculation unit and a quality determination unit. The standard deviation value calculation unit calculates, in a predetermined calculation cycle, a standard deviation value of a reflected beam detection value at a monitoring wavelength from among reflected beam detection values in a predetermined wavelength band output from the reflected beam detector. The quality determination unit determines whether or not a burning defect has occurred in which a cut surface of the sheet metal is excessively melted based on a comparison result of comparing, with a first threshold value, the standard deviation value calculated by the standard deviation value calculation unit.
摘要:
A component having a first part and a second part. The first part has a first interface surface and the second part has a second interface surface that is connected to the first interface surface via a bond. A digital profile of the first interface surface is used to shape the second interface surface to fit against the first interface surface with minimal to no gap therebetween before forming the bond. The digital profile is developed by scanning the first part with a scanner and the second part is shape by cutting or milling with a robotic arm that acts in accordance with a digital profile data read by a controller. The two parts are bonded via a weld that is automatically guided by the digital profile.

A method processes a belt with a belt body that has a first surface and a second surface connected to each other by side surfaces. Each side surface is smaller than each surface. At least one of the surfaces of the belt is coated with a coating having at least one layer. In a step i) the coating is interrupted or left out in a region of the belt to be processed, and a recess, in particular a gap-shaped or hole-shaped recess, interrupting the coating is produced in the region to be processed, which recess is at least partially delimited by opposite sections of the at least one coating. In a step ii) directly thereafter or after further intermediate steps, the recess is at least partially filled up with at least one material of the same type as that of the at least one layer of the coating.

Laser cutting on a plated steel sheet is executed by cutting the plated steel sheet by irradiating the plated steel sheet covered with a plate metal with laser light at a wavelength in a 1 micrometer band; and emitting assist gas onto a cut surface of the plated steel sheet, the cut surface being formed. in the step of cutting, to make the plate metal fused by irradiation of the laser light flow to the cut surface so as to cover the cut surface with the plate metal.

The disclosure relates to methods and apparatuses for controlling a cutting process in which a workpiece is cut by a high-energy beam. A process light signal is detected emanating from an interaction region of the high-energy beam with the workpiece in a first wavelength range (Δλ1), in which at least one metallic constituent (Fe, Cr) of the workpiece has at least one emission line, and in a second wavelength range (Δλ2), which differs from the first wavelength range, in which continuum radiation of the workpiece without emission lines is detectable. Vaporization of the at least one metallic constituent (Fe, Cr) is monitored on the basis of an intensity of the process light signal detected in the first wavelength range (Δλ1) and on the basis of an intensity of the process light signal detected in the second wavelength range (Δλ2).

A floating chuck assembly used in connection with a workpiece support carrying a workpiece, the floating chuck assembly comprising a chuck assembly; a linkage assembly adapted to support the chuck assembly, the linkage assembly including a mounting link attachable to the chuck assembly, a first link having a first end pivotally attached to a support about a first support axis and having a second end pivotally attached to the mounting link about a first mounting axis, a second link having a first end pivotally attached to the support about a second support axis and a second end pivotally attached to the mounting link about a second mounting axis; and, an extendable support having a first portion attached to the support and a second portion attached to one of the mounting link, first link, and second link, wherein the first portion moves relative to the second portion.
摘要:
A method for manufacturing electrical connections in wafer is provided. A plurality of openings is formed on the upper surface of a wafer by dry etching or laser drilling and then solder paste is applied to the openings. Next, the wafer is positioned in a vacuum environment and is heated to soften the solder paste. Subsequently, the vacuum is suddenly broken to have the pressure upon the upper surface of the wafer greater than that in the openings thereby pressing the molten solder paste into the openings.
摘要:
A process and apparatus for manufacturing structural steel metal products in which a strip of sheet metal is fed along a plane and cut by a laser into a number of sheets with each sheet secured to a respective supporting surface of a rotary work holder and welded by an additional laser to the previous sheet along a common edge.
