METHOD FOR 3D-MODELING BLADE USING 3D CAD SYSTEM

摘要

PURPOSE: A method for 3D(Dimensional)-modeling a blade using a 3D CAD(Computer Aided Design) system is provided to precisely perform modeling of a vane by applying a tool using the 3D CAD system. CONSTITUTION: The XYR data for each section of a vane is inputted(S101). A curve of each section of the vane is made by using the inputted XYR data(S102). An SP(SPline) curve is made(S103). Each section of the vane is modeled(S104). A guide SP line is made(S105). A shape of a surface and a body for the vane is completed(S106).
