Abstract
A method of manufacturing cooled aerofoil blades in which blade parts are bonded together to provide complete blades. The blade parts are provided with mating surfaces which are simultaneously spark erosion machined to match the same prior to the blade parts being brazed together. Spark erosion machining is performed by maintaining the mating surfaces to be matched at a constant distance apart from each other and translating a tensioned wire electrode along a path passing mid-way between the mating surfaces.
