An apparatus and method regarding forming a cooling hole in a component for a turbine engine, with the component held in a hole-forming machine with a laser carried on a multi-axis carriage and defining an optical path, the method comprising forming a set of cooling holes in the component with a laser mounted to the multi-axis carriage, estimating a total airflow through the set of cooling holes based on a set of data regarding the flow effectiveness of the set of cooling holes, and forming a second set of cooling holes with the laser.

Method of forming cooling holes

A method for making shaped cooling holes in a substrate by pulsing and stopping a laser while moving the laser or substrate. The method produces shaped cooling holes with a bore angled relative to an exit surface of the combustor liner. One end of the bore is an inlet formed in an inlet surface of the combustor liner. The other end of the bore is an outlet formed in the exit surface of the combustor liner. The outlet has a shaped portion that expands in only one dimension.
