This paper takes the machining surface morphology obtained by milling aeronautical hard-to-cut nickel-based superalloy GH4169 as a research object with ceramic tools,and uses the milling parameters in the engineering field as orthogonal experimental analysis data to compare and analyze each group of process parameters.The surface morphology of the workpiece is optimized for cutting process parameters when obtaining the best surface morphology,and is verified by experiments.A mathematical model is established for the lateral texture of the surface of the processed workpiece and the correctness of the model is verified through experiments.This paper provides experimental basis and data support for the cutting and forming technology of the key parts of this material in the aerospace field,and has important engineering guidance significance.
