A combustor component with cooling apertures has the apertures formed by laser drilling. The machining apparatus comprises a beam generator (16) for generating a beam (14) for directing at the combustor component and a beam trap (10,12). The component is translated relative to the beam (14) and the beam (14) is directed to the beam trap (10,12) and is dissipated within the beam trap (10,12). |
