Applying Computer Aided Designing for Steam Turbine Blade

Modern industries are using CAD models for the accurately representation of geometry for designing and manufacturing of turbines. The CAD model provide a more realistic analysis of performance of the product, this task included dimensional measurement and geometric modeling. This paper presented the procedure for how to achieve CAD model of turbine blade. The method discussed here is the latest profile developed for blades involves regularization and curve fittings using Bazier and B-spline curve generation . Weighting coefficients and nurbs are used for curvature surface of the model. KeywordsCascade; Blade;
