【Abstract】 Aiming at the problem that the traditional analytical method is very difficult to calculate the shape of the disc milling cutter for screw surface machining, the solving strategy of using the theory of numerical simulation of conjugate surface is proposed. Transforming the calculation problem of the profile of the disc milling cutter for screw machining into an unconstrained optimization problem, the solution idea and specific implementation method based on genetic algorithm are proposed, the specific measures to promote convergence are given, and the solution process and results are analyzed. The results show that the genetic algorithm can reliably achieve the optimal solution(sub-optimal solution)of the unconstrained optimization problem, which can provide a simple method and feasible way for the accurate profile of the disc milling cutter for screw machining.更多还原
