By that we can get some experiences about the techniques of product design and manufacturing. The development of propeller inspection techniques can not only provide the data points of the same radius of blade section, but also increase the efficiency of propeller inspection. This work focused on the development of an integrated approach, by combining three-dimensional digitization, reverse engineering and CAD/CAM technology, for the reconstruction of complete CAD models. Besides, applying propeller inspection techniques to get the blade data. With the blade data we can calculate the parameters of the propeller blade and evaluate the shape error of each blade.This work describes the approaches of 3-D coordinate measurement and CAD model reconstruction. Applying the equal radius inspection approach to get digitalized propeller blade information, and performing mathematical calculations to evaluate the blade section parameters.
