Beschreibung
Zusammenfassung:	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.
