The invention relates to the technical field of three-dimensional measurement, in particular to a linear structured light bearing bush and gear three-dimensional measurement method and system, and the method comprises the following steps: 1, data collection: employing a CCD camera arranged on a measurement platform to shoot laser images containing laser line patterns from different angles; step 2, image processing: extracting feature points in the laser image by using a computer vision algorithm; and 3, three-dimensional reconstruction: based on the known CCD camera parameters and the position change of the feature points on the to-be-measured object, obtaining three-dimensional data of the to-be-measured object by using a space coordinate conversion technology. And step 4, error correction: carrying out error analysis on the obtained three-dimensional data. And step 5, result output: outputting final three-dimensional measurement data of the to-be-measured object based on the corrected result. Through the automatic and intelligent measurement means, the measurement period can be further shortened, and the production efficiency is improved.

The present invention discloses a non-circular aircraft engine lip spinning forming method, which belongs to the field of spinning forming technology. The non-circular aircraft engine lip spinning forming method includes the following steps: pre-treatment of the blank, stabilization treatment of the blank; design and manufacture of spinning tooling, design of supporting core mold according to the shape of the part; spinning trajectory design and program compilation; simulation verification; hot spinning forming. The present invention can break the limitations of the traditional spinning process, and use the calculation method of discrete increments to discretize the surface trajectory into a curve trajectory, and discretize the curve trajectory into a point set. Through a CNC spinning machine tool, the asymmetric spinning forming of the lip part is realized. The present invention only needs one set of spinning molds to complete the forming, which greatly reduces the mold cost and improves the forming accuracy compared to stamping forming. At the same time, it can realize integrated forming without the need for petal separation and assembly.
