Filed:

Mar 12, 2020

Appl. No.:

16/817147

Inventors:

- Chula Vista CA, US
Angel Cabrera - Fullerton CA, US
Fassil Ghebremichael - Irvine CA, US
Charles Novak - Perris CA, US
Dominic J. Elliott - Riverside CA, US
Andrew Adan - Corona CA, US

Assignee:

ROHR, INC. - Chula Vista CA

International Classification:

B23K 26/38
B23K 26/04
B23K 26/067

Abstract:

A perforation system is disclosed that utilizes an optical beamlet generator and a scanner (e.g., at least two moveable mirrors). The optical beamlet generator may be a lenslet array or a diffractive optical element. The optical beamlet generator outputs a plurality of beamlets from a single input laser beam. These beamlets are moved in at least two dimensions relative to a surface of a substrate to form perforations in the substrate.

International Classification:

G02B 26/12
G02B 26/10

Abstract:

Various arrangements and methods are disclosed for forming one or more perforations on a substrate surface using a laser system, at least one rotating polygon mirror, and at least one other movable mirror. A rotating polygon mirror may be used to define a plurality of perforations in a row set or band on a substrate surface by incrementing (e.g., moving) a first mirror between a plurality of fixed (e.g., pointing) positions. A rotating polygon mirror may be used to define a plurality of perforations in a row set or band on a substrate using a first mirror that is maintained in a fixed (e.g., pointing) position. A first rotating polygon mirror and a second rotating polygon mirror may be used to define a plurality of perforations in a row set or band on a substrate surface, where the first and second polygon mirrors are used to define an extent of a given perforation in two dimensions on the substrate.

Inventors:

- Chula Vista CA, US
Angel Cabrera - Anaheim CA, US
Charles Novak - Moreno Valley CA, US

International Classification:

B23K 26/40
B23K 26/03
B23K 26/08
B23K 26/36

Abstract:

Manufacturing methods are provided. During one of these manufacturing methods, a composite part is freely arranged on a support surface. The freely arranged composite part is scanned using a scanning system to provide command data. The freely arranged composite part is machined using a laser based on the command data.
