Integrated analysis method of thin-walled turbine blade precise machining

Conventional turbine blade machining technology has to face some challenges on production efficiency, quality and environmental impact. So a new machining technical solution for thin-walled turbine blade is presented. Technical problems associated with the precise machining of turbine blade are discussed in detail. On the basis of analysis with existing demerits, we propose a new fixture optimization and precise machining schema for turbine blade. In the proposed technical methodology, geometric locating tolerance analysis and FEM based structural deformation prediction methods are integrated into one framework to improve the machining performance of thin-walled turbine blade. An automatic machining station of turbine blade is also developed. Promising technical capability of this system is demonstrated and validated by real machining experiments.
