Abstract (en)
A method of forming a turbine nozzle guide vane (2) for a gas turbine engine, the guide vane (2) comprising an internal cavity (14) and having internal features (16), comprises investment casting metal around a core member (30) that defines the internal cavity (14) and internal features (16) of the guide vane, removing the core member (30), and machining the guide vane (2). The process of investment casting around the core member (30) includes the step of casting at least one feature (40) external to the guide vane (2). The external feature (40) is used as a reference point to indicate the location of the internal features (16) of the guide vane (2) during the machining of the guide vane (2).
