提出了一种复杂曲面类毛坯与设计原型最佳适配的优化算法.通过曲面的旋转、平移以及改进的多目标优化算法,完成了毛坯预定位、精调整以及细微处理,使得毛坯与理论曲面尽可能吻合,从而达到了改善加工余量分布的目的,并且减少了毛坯的堆焊量,大幅度提高了生产效率
An optimization algorithm for the best fit of a complex curved surface blank and a design prototype is proposed.The pre-positioning, fine adjustment and fine processing of the blank are completed by the rotation, translation and the improved multi-objective optimization algorithm, so that the blank and the theoretical surface As far as possible consistent with, so as to achieve the purpose of improving the distribution of the allowance, and reduce the blank of the surfacing, a substantial increase in production efficiency
