Research On Model Building And Cutter Path Of Turbine Blades

Turbine blades are typical parts with complex surfaces, as the part of the steam turbine machinery, processing quality and efficiency of blades play a leading role on turbine safety and economy. Therefore, the study on modeling and tool path of steam turbine blade has important practical significance. In this thesis, the solid model of turbine blades was established by using Pro / E, and assembly of various components was completed; then according to NURBS curve and surface theory, turbine blade surface geometry modeling was completed by using MATLAB, and based on it the tool-path calculation and generation were finished; Finally, machining simulation was carried out by using the CAM function of Pro / E to generate the NC machining code, and the actual processing of the turbine blade model was completed by the processing center.
