Research on high-efficiency positioning technology for complex curved blades in aero-engines

Abstract To realize the accurate positioning of the machining position of micro holes in aviation blades, this paper first proposes a six-point positioning optimization algorithm to construct the exact position of blade pose. Then, based on the requirements of precise coordinate positioning and man-machine friendliness, the cam system is built. Finally, the accuracy of the algorithm is verified by process experiments. After three iterations in the experiment, the error is less than 0.005 mm. The experimental results show that the positioning technology has the advantages of high positioning efficiency and high accuracy.
