摘　　要：针对水室封头数控加工存在成本高、效率低、加工难等问题,建立了以最小刀具寿命消耗和最大生产效率为优化目标的水室封头数控加工参数优化的数学模型。利用遗传算法(GA)求得最优组合切削参数,实验验证了优化结果的合理性,提高了生产效率。Nuclear power head is difficult to be manufactured, with high cost and low efficien- cy. This paper proposes a mathematical model for optimization of parameters in the numerical con- trol process of a power head. The objective is to achieve the best productivity and the longest tool life. Genetic algorithm is used to optimize the machining parameters. Experimental studies show that the optimized results are reasonable, with improved efficiency of the power head.
