Abstract：

In order to improve the accuracy of measuring complex titanium alloy forging blades and the data density of front and rear edge positions with the holographic cone light sensor, a method of measuring path planning for complex titanium alloy blades was proposed. Based on the introduction of the concept of key points on the blade section line, the maximum thickness and the middle arc of the blade section line were calculated by using the cubic rational spline function, and eight key points such as leading edge point, trailing edge point and intersection of the maximum inscribed circle were obtained. Furthermore, the eight key points were used to segment and extend the section lines, and then a bi-directional adaptive path planning method was proposed. The proposed method was applied to the developed four-axis precision blade measuring equipment, and the feasibility and effectiveness of the method were verified by experiments. The experimental results show that the proposed method can provide high-precision 3D reconstruction data for adaptive machining of precision forging blades.
