Digitized Modeling Technology of Turbine Blade

The digitized modeling technology of turbine blade is input data of turbine blade casting mold. Due to the complexity of the turbine blade structure, it is much difficult to model the 3D parametric directly as a whole structure. The digitized modeling technology of turbine blade is input data of turbine blade casting mold. Due to the complexity of the turbine blade structure, it is much difficult to model the 3D parametric directly as a whole structure. The problem can be simplified by adopting structure decomposition, building, respectively, corresponding features of the decomposing structures and combining them with Boolean operations. The classification of blade structural features and the parametric modeling of structural features are introduced in this chapter.
