Abstract

A method of and apparatus for forming a through bore or recess in a turbine blade, for a lacing wire hole for example, includes a machine capable of approaching the area to be machined in a first direction during which an initial machining operation may take place and them moving in a second direction completing the machining operation. Support means are provided to ensure the blade is held firmly. The method and apparatus permit of accurate machining of blades when they are in an array of blades still secured to the rotor.
