The invention discloses a hole group machining path optimization method based on small-world network searching. The method includes the steps that when hole groups are machined, an initial antibody population A is generated randomly, and each antibody in the initial antibody population A corresponds to one machining sequence of holes; the initial antibody population A is evaluated according to theoptimization condition, and elite antibodies in the initial antibody population A are reserved to form an antibody population B; each elite antibody in the antibody population B is subjected to clonecopying, so that an antibody population C is obtained; elite antibodies in the antibody population C are subjected to small-world network searching operation, short-range optimization operators and long-range optimization operators are included, and accordingly an antibody population D is obtained; each elite antibody in the antibody population B is subjected to quantum crossover, so that an antibody population E is obtained; high-quality antibodies are selected from the elite antibodies of the antibody population D and the antibody population E to form an antibody population F; and whether terminal is required or not is judged. By adoption of the method, a small-world network searching model is combined with a cloning selection method, the machining path length can be decreased, the machining speed is increased, and the reverse conversion frequency of cutters is reduced.
Description
technical field [0001] The invention relates to the field of numerical control machining control in mechanical engineering. More specifically, the present invention relates to a method for optimizing machining paths of hole groups based on small-world network search. Background technique [0002] The small-world phenomenon originated from social psychologist Milgram's research on tracking the shortest path in American social networks in the 1960s. Studies have shown that there are a large number of shortest paths in the social network, and through these shortest paths, information can be quickly transmitted to any destination, which is the famous six degrees of separation inference. After that, complex network research entered a new era, and a large number of research results emerged, which were successfully applied in many fields such as Internet control and biological protein network dynamics research. Scholars have proposed to use the transmission characteristics of the...
