Abstract: |
Taking the processing of an aerospace engine turbine disk as an example, the application of WEDM process in the machining of the turbine disk is analyzed according to the requirements of material properties, structure characteristics and technology. Compared with the traditional processing methods, the advantages of the special processing technology in aerospace engine manufacturing are summed up. Based on the research on the characteristics and processing process rules of the cutting process, a set of new processing methods and processing parameters are summed up through the experimental research, and the technical means are given to realize the whole plate processing. It opens up a new approach for the precise machining of turbine disk mortise and tenon for aerospace engines. |
