Advanced Machining Technology for Gas Turbine and Heat Engine Components

Article Preview

Abstract:

Cost effective ceramic manufacturing with green and dense machining perspectives has been described. An advanced CNC green machining based complex shape forming technology developed at Saint-Gobain is described which has been shown to be robust and capable of rapid prototyping. Utilizing a systems approach involving green blank properties, type of cutting tools and machining parameters the procedure has been optimized. Integral Bladed Rotors (IBR) for microturbine applications have been fabricated with dimensional controls within 0.15% and successfully spin tested at 143330 rpm without failure. Following this approach, a cost effective machining and prototype fabrication procedure is under development for IBR and Vane rings for various civilian and military applications.
