[0052] With the rapid development of modern technology, the aircraft manufacturing industry gradually changes into digital manufacturing, efficient and high-quality manufacturing production. Numerical control machining is one of the most important methods to ensure the machining quality and precision of aircraft parts. Numerical control machining refers to a process method of part machining on a numerical control machine tool. The process plan of numerical control machine tool machining and traditional machine tool machining is consistent in general, but there are also obvious changes. Numerical control machining is a mechanical machining method for controlling the displacement of parts and tools by digital information. It is an effective way to solve the problems of variable part types, small batch size, complex shape, high precision and realize efficient and automatic machining. Numerical control programming is the basis of numerical control machining. The quality and efficiency of numerical control machining program are important factors to determine the machining quality and efficiency of aircraft parts.

[0053] CAD / CAM technology has been widely used in the manufacturing of aircraft structural parts, greatly improving the programming efficiency of parts. However, there are many rotary parts in aircraft parts, most of which are transmission parts, which are an important part of aircraft parts, and are often machined by turning. At present, manual programming is still mainly used for turning machining in China, which mainly relies on the accumulation of programming personnel's rich numerical control machining process knowledge and process experience, and has high requirements for the programming ability of programming personnel, low work efficiency and unstable programming quality.

[0054] Therefore, the present application provides a solution based on the machining features of aviation rotary parts, establishes a machining feature model based on part families, and forms a part machining database, effectively integrating the various types of aviation rotary parts, enabling the formation of standardized and parameterized turning machining programs, improving programming quality, achieving automation of aviation rotary part programming, and thus shortening production cycle and improving production efficiency. The geometric feature analysis of the designed part obtains the part family classification, part size and part material. According to the part family classification, the corresponding machining feature model is selected in the part machining database, and the feature elements of the designed part (part family classification, part size, part material) are input, to directly obtain the parameterized numerical control G code program (primary turning machining program). The program is simple and easy to read, and optimizes the tool path and cutting parameters, effectively solving the problems of low programming efficiency and unstable programming quality, improving the programming efficiency and ensuring the programming quality. Further, simulation verification ensures the accuracy of the turning machining program.

[0086] In the specific implementation process, the step of obtaining the machining feature model includes: decomposing the part structure of each part family into multiple machining features through geometric analysis, each machining feature is compared and identified with each typical machining feature, the parameters of the matched typical machining feature are assigned to the machining feature, each machining feature is matched with a corresponding parameter to form a machining feature parameter of the part family. According to the machining performance of different part materials, the machining feature parameter is adjusted to form an adjusted machining feature parameter of the part family under different materials. The adjusted machining feature parameter includes cutting parameters such as spindle speed S, rough and fine machining feed rate, and single-side cutting depth. According to the numerical control turning programming specification of each rotary part, a standardized machining process sequence of the part family can also be constructed in combination with the machining process experience of experienced turning programming personnel to form a standardized process flow.
