Study of CAD modeling for turbine blade profile based on reverse engineering

It discusses a method of CAD modeling for turbine blade profile based on reverse engineering technology,in which the significance of modeling the turbine blade profile is analyzed by applying reverse engineering.It briefly introduces the method for collecting reverse engineering data and its classification.Then the mathematical model for complex curve and profile is stated.Furthermore,the processing methods and procedures of blade point cloud data made with software Imageware combinig the modeling of blade profile by using Pro/E software are demonstrated.Meanwhile optimization of the blade profile is proposed by application of Pro/E software,on which the turbine blade profile shall be machined on NC machine.
