摘要: 在金属切削加工过程中,刀具磨损直接影响加工精度与效率,对铣削加工过程中的工艺参数进行动态优化至关重要。针对该问题,提出了一种考虑刀具磨损的精密零件铣削工艺参数优化方法。首先,利用正交实验分析主轴转速、每齿进给量和切削深度对刀具磨损的影响规律;然后,以刀具耐用度、材料去除率为优化目标,通过遗传算法(Genetic Algorithm,GA)对工艺参数进行优化;最后,通过精密零件铣削实验验证了所提方法的有效性,实验结果表明,材料去除率提升了21 %,每加工7 000 mm,刀具磨损下降了17.49 μm,刀具耐用度提升了21.4 %,优化效果显著。

Abstract: During the metal cutting process,tool wear directly affects machining accuracy and efficiency,and is crucial for the dynamic optimization of process parameters in milling operations. To address this issue,a method for optimizing milling process parameters of precision parts considering tool wear was proposed. Firstly,orthogonal experiments were conducted to analyze the influence laws of spindle speed,feed per tooth,and cutting depth on tool wear. Secondly,with tool life,material removal rate as optimization objectives,the process parameters were optimized using a genetic algorithm.Finally,the effectiveness of the proposed method was verified through milling experiments on precision parts. The experimental results show that the material removal rate was increased by 21 %,tool wear was reduced by 17.49 μm per 7 000 mm,and tool life was improved by 21.4 %,demonstrating significant optimization effects.

Key words: tool wear, milling, process parameter optimization, Genetic Algorithm(GA)
