Abstract

The blade is a key component of the aero-engine. As the blade must have a precise size, accurate shape, the three-dimensional profiling measurement of the blade is very important. Its complexity and diversity bring considerable difficulty to the measurement. The optical triangulation method is used in the profiling measurement of the blade in the paper. The coded technique based on gray-code combined with the phase-shift method is used. The three-dimensional point cloud of blade is obtained in this method. A high accuracy of three-dimensional profiling measurement of the blade is achieved, and the measurement accuracy reaches 0.05 mm.
