In order to solve the problems of more optional processing parameters,difficult to ensure the quality and efficiency in the processing of turbine blade.A five-axis machining process for turbine blade was proposed.A theoretical model of cutting force was established by analytical analysis method,and the model accuracy of cutting force empirical formula was compared and verified.Combined with the finite element model of workpiece force and deformation,the optimized cutting parameters were selected,and the program of unbiased swing point milling and side milling of blade was programmed and simulated by using visual software.The visual simulation results show that the blade surface with high machining accuracy can be obtained under the machining process and parameters.The point milling method has high machining accuracy,strong versatility and low efficiency compared with the side milling method.The milling experiments results show that the simulated surface is in good agreement with the experimental surface on the law of variation,and the effectiveness of the proposed process and parameters is verified.The manufacturing accuracy and efficiency of turbine blades are improved.
