Four Axis NC Machining Turbine Blade Method Research

摘要

The steam turbine blade is one of the important parts of steam turbine, its quality fit and unfit quality directly impact on the performance of steam turbine. Turbine blade has its type surface complex, requiring precision higher and other characteristics, so it was a difficult problem in the field of machinery manufacturing. Therefore, how to adopt appropriate methods to improve the manufacturing quality of blade is of great significance. This paper has discuses the big distortion, the variable cross-section of turbine blade NC machining method, completed numerical control simulation and all the process and post processing in Cimatron E8.5 software environment. For similar modalities surface parts of NC machining provided a good idea.
