Abstract：

The three-dimensional mathematical model of 3D mesh stamping part constructed by reverse engineering was explored. In this method，the 3D mesh stamping part was non-contact measured by laser three-coordinate scanning measuring instrument, and the point cloud data of 3D mesh stamping part was obtained. Then the data fitting for point cloud was completed by Geomagic, and the digital model for 3D mesh stamping part was obtained. Compared to disadvantages of slow speed and poor accuracy of the traditional contact measurement for 3D mesh stamping parts，such as the three-coordinate measuring machine(CMM), the speed is faster and the precision is higher by the laser three-coordinate scanning measuring instrument. In addition, the digital 3D model data fitted by Geomagic is closer to the actual model which showes the feasibility of the proposed method.
