摘要
基于面齿轮传统机械加工精度欠佳的局限性,最后工序采取飞秒激光对面齿轮进行精修加工,在满足面齿轮烧蚀深度和齿面粗糙度约束的前提下,建立了以飞秒激光精修效率和表面质量为目标函数的多目标优化数学模型。利用内点罚函数并行以gamultiobj函数为基础的改进遗传算法求解优化模型,得到两组较优的飞秒激光加工面齿轮参数方案,与参数优化后的激光实验结果相对比,最大相对误差均在合理范围内,证明了优化的合理性,提供一定的理论指导在实际生产领域对飞秒激光精修面齿轮的运用。
Based on the limitations of the traditional machining of face gears,the final process of face gear finishing by femtosecond laser is carried out,and a multi-objective optimization mathematical model with femtosecond laser finishing efficiency and surface quality as the objective functions is established under the premise of meeting the constraints of ablation depth and tooth surface roughness of face gears.Two sets of optimal parameter schemes for femtosecond laser machining of face gears are obtained by solving the optimization model using an improved genetic algorithm based on the gamultiobj function in parallel with the interior point penalty function.In comparison with the experimental results of the laser after parameter optimisation,the maximum relative errors are within a reasonable range,providing the rationality of the optimization,and some theoretical guidance is provided for the application of femtosecond laser finishing face gears in practical production.
