Abstract

See full text

A method for manufacturing an airfoil is provided, the method including drilling a hole in a near wall of the airfoil using a laser drill and activating a back strike protection in a cavity of the airfoil. The method additionally includes detecting a breakthrough of a laser from the laser drill through the near wall of the airfoil and subsequently initiating a drilling subroutine, with the drilling subroutine including a continued operation of the laser drill. Such a method may provide for an improved hole, such as a cooling passage, in the airfoil.
