Method and device for selecting cutting parameters of curved surface of high-temperature aluminum alloy inner cavity

The embodiment of the invention discloses a method and device for selecting cutting parameters of a curved surface of a high-temperature aluminum alloy inner cavity. The method comprises the following steps that a plurality of preset cutter cutting paths are acquired; for each cutter cutting path, multiple sets of set cutting parameters are adopted to conduct cutting treatment on the high-temperature aluminum alloy inner cavity curved surface according to the cutter cutting path, and cutting effect parameters corresponding to each set cutting parameter are obtained; and according to the cutting effect parameters, target cutting paths in the multiple cutting paths and target cutting parameters in the multiple sets of set cutting parameters are determined, and the target cutting paths and the target cutting parameters serve as the cutting paths and the cutting parameters of the high-temperature aluminum alloy inner cavity curved surface. According to the embodiment of the invention, the optimal cutting path and
