Abstract Thin-walled blades are widely used in aviation and aerospace industry, the measurement and modeling are the key process of reverse manufacturing. According to geometric features of blade, contour measurement method is used to measure blade surface. The key technology of modeling process is studied. The works on measurement and modeling of blade surface are carried out, including the method of the probe radius compensation, eliminating of bad points, creating the leading and trailing edge by single-arc method, creating the section curves of the suction side and the pressure side by NURBS curve method , jointing section curves of suction(pressure) side and the leading(trailing) edge, and creating of the equidistant curves. Finally, a solid model is generated through a measurement example, and the quality and precision of blade surface are excellent. This method is proved simple and easy to apply.
