According to the structure characteristics of the turbine blade,aiming at the difficulties in processing and testing,the method that the multiaxis machining function of UGNX 8.5 software was used to make tool path planning,generation,simulation and post processing was expounded.The 3D laser scanning technology was used to scan completed part and the data file of point cloud was gotten.Reverse software Geomagic was used to process the cloud data,the surface model was put out,then it was matched with the blade theory model,so as to detect whether the part met the design requirements.The processing and detection scheme is practical and has a certain reference value.
