Abstract

A method for disposing blocking material within an interior of a component for blocking a beam of radiation from a laser during a laser drilling operation, the method including forming one of a multiple of apertures formed via a first process and forming the remainder of the multiple of apertures formed via a laser drilling process. A component for a gas turbine engine includes a surface with at least one of a multiple of apertures formed via a first process, the at least one of the multiple of apertures formed via the first process in communication with a cavity, a remainder of the multiple of apertures formed via a laser drilling process, the remainder of the multiple of apertures in communication with the cavity.

First claim

What is claimed:

1. A method for disposing a blocking material within an interior of a component, the method comprising:
forming at least one aperture of a multiple of apertures in communication with a cavity within a component via a first process;
filling the cavity with a blocking material subsequent to forming the at least one aperture formed via the first process and prior to forming the remainder of the multiple of apertures via a second process different than the first process, wherein the second process is a laser drilling process and the at least one aperture allows a route for entrapped gasses from the blocking material to escape the cavity; and
forming the one of the multiple of apertures formed via the first process a maximum distance from where the blocking material is injected into the cavity.

2. A method for disposing a blocking material within an interior of a component, the method comprising:
forming at least one aperture of a multiple of apertures in communication with a cavity within a component via a first process; and
filling the cavity with a blocking material subsequent to forming the at least one aperture formed via the first process and prior to forming the remainder of the multiple of apertures via a second process different than the first process, wherein the second process is a laser drilling process and the at least one aperture allows a route for entrapped gasses from the blocking material to escape the cavity; and
filling the cavity with a blocking material until the blocking material at least partially excretes through the one aperture formed via the first process.

3. A method for disposing a blocking material within an interior of a component, the method comprising:
forming at least one aperture of a multiple of apertures in communication with a cavity within a component via a first process; and
filling the cavity with a blocking material subsequent to forming the at least one aperture formed via the first process and prior to forming the remainder of the multiple of apertures via a second process different than the first process, wherein the second process is a laser drilling process and the at least one aperture allows a route for entrapped gasses from the blocking material to escape the cavity, wherein the one aperture formed via the first process is at a maximum distance from where a blocking material is injected into the cavity.

4. A method for disposing a blocking material within an interior of a component, the method comprising:
forming at least one aperture of a multiple of apertures in communication with a dead end cavity via a first process;
filling the dead end cavity with a blocking material subsequent to forming the at least one aperture formed via the first process;
forming the remainder of the multiple of apertures in communication with the dead end cavity via a second process subsequent to filling the dead end cavity with the blocking material, the second process comprising a laser drilling process; and
forming the one of the multiple of apertures formed via the first process a maximum distance from where the blocking material is injected into the cavity.

5. A method for disposing a blocking material within an interior of a component, the method comprising:
forming at least one aperture of a multiple of apertures in communication with a dead end cavity via a first process;
filling the dead end cavity with a blocking material subsequent to forming the at least one aperture formed via the first process;
forming the remainder of the multiple of apertures in communication with the dead end cavity via a second process subsequent to filling the dead end cavity with the blocking material, the second process comprising a laser drilling process; and
forming the one of the multiple of apertures formed via the first process at a location to provide a vent for the blocking material.

6. A method for disposing a blocking material within an interior of a component, the method comprising:
forming at least one aperture of a multiple of apertures in communication with a dead end cavity via a first process;
filling the dead end cavity with a blocking material subsequent to forming the at least one aperture formed via the first process; and
forming the remainder of the multiple of apertures in communication with the dead end cavity via a second process subsequent to filling the dead end cavity with the blocking material, the second process comprising a laser drilling process, wherein the cavity includes a multiple of chambers, each of the chambers including one of the multiple of apertures formed via the first process.
