Abstract:
A method of machining a turbine component using a cutting tool assembly and a lathe, the turbine component including a rotational axis, a central bore, an inner wall, at least one weld, and weld flash that is adjacent a weld on the inner wall, said method comprising:providing a cutting tool assembly including a centerline axis, a solid toolblock body, a lead screw, a blade sub-assembly, and a cutting insert, said toolblock body having a solid center portion extending axially between said lead screw and a shank used for coupling the toolbody to a lathe; positioning the toolblock body in the lathe such that the lathe controls the cutting tool assembly; positioning the cutting tool assembly within the turbine component central bore; extending the blade sub-assembly to be adjacent the turbine component inner wall by rotating only a single component of the cutting tool assembly; rotating the turbine component about the rotational axis; and moving the cutting tool assembly centerline axis about the turbine component rotational axis such that the flash is removed using the cutting insert.
