Abstract: The right choice of cutting parameter is the key to improve production efficiency and reduce power consumption.To select the cutting parameter of turning machining rightly,a turning parameter optimization method based on game theory was proposed.Aiming at the problem of turning parameters optimization selection,the highest production efficiency and the lowest power consumption was taken as the optimization goal by using the features of game theory and conflict solution,and the multi-objective optimization problems of turning parameter selection were transformed into the decision based on game theory problem.The multi-objective optimization mathematical model of efficiency and power consumption was transformed into the corresponding non-cooperative game decision-making model through establishing the players,payoff function and classifying the strategies,and the algorithm for solving Nash equilibrium strategy based on the model was given,which had selected a better combination of turning parameters.The effectiveness of the established game optimization model was verified by optimization analysis of an example and comparison with genetic algorithm and the linear weighted sum method.
