The invention relates to the technical field of production cutting, in particular to a cutting path planning method and system for large-scale blanking, and the method comprises the following steps: forming vertexes of parts in a layout drawing into a set, and obtaining vertex numbers; randomly generating an initial fish school by applying an artificial fish school algorithm; updating the fish school, continuously iterating the fish school, and finding out a current optimal solution; using a vertex code in the current optimal solution as an initial solution, and using a disturbance operator to disturb the initial solution; locally searching a solution after disturbance by using a variable neighborhood down-regulation operator; continuously and repeatedly disturbing the current solution and carrying out local search until the number of iterations is met to obtain a vertex set, and sequentially connecting points in the set to form a cutting path; cutting the layout drawing according to the cutting path, and sep
