Abstract
AbstractTurbine blades have complex shapes and surfaces. It is difficult to obtain the overall model of an unknown turbine blade quickly. A method of reverse engineering combined with 3D printing technology is proposed to solve the problem of rapid design and manufacturing of complex curved parts. We use a scanner to scan turbine blades and extract point cloud data. Geomagic Wrap and Geomagic Designx software are used for data processing and 3D model reconstruction, and the model accuracy is analyzed. 3D printing technology is used to complete the rapid production of turbine blades. The blade is measured by coordinate measuring machine (CMM), and the precision is compared with that of 3D model. The results show that the precision of turbine blade model made by reverse engineering technology and 3D printing meets the design requirements. This method can shorten the development period of turbine blades and reduce the trial production cost.KeywordsRapid manufacturingReverse engineering3D printing
