A tool,for disposing laser blocking material,on the interior of an airfoil,is disclosed. Various construction details are developed which speed the process. In one detailed embodiment, the tool has reciprocatable jaws,which open and close to urge a mask,into engagement with the airfoil.

Tool for disposing laser blocking material in an airfoil

A method for orienting an airfoil,during filling of an airfoil with laser blocking material,prior to a laser machining operation is provide and includes making a mask,for the airfoil.

Method for orienting an airfoil for processing and for forming a mask for the airfoil

A process and apparatus for selectively electroplating the tip portion of an airfoil. The airfoil includes a root portion and a blade portion having a tip. At least part of the blade including the tip is coated with an insulating material. Insulating material is removed from the tip and the airfoil is mounted in a fixture so that the tip is exposed. The fixture is immersed in a sealing bath, and the fixture and at least a portion of the airfoil is encased in sealing material while leaving the tip exposed. The fixture is then immersed in an electroplating bath, the exposed tip is electroplated, and the fixture is removed from the bath. The fixture includes an elongated base member and a grip element supported on the base member. The grip element is made of a flexible material and has a plurality of slots configured for receiving the root portion of the airfoils. An electrical contact is provided in each slot so as to contact the root portion of the airfoil. A plurality of fixture may be mounted on a carousel.

Apparatus for selectively electroplating an airfoil

A fixture 56 for disposing laser blocking material 52 on the interior of an airfoil 10 is disclosed. Various construction details are developed which allow for the repetitive disposition of the laser blocking material in one airfoil after another. In one embodiment, the fixture includes a sprue plate 62 and locating block 126 which are spanwisely spaced and engage the ends 14, 18 of the airfoil.
