摘要
作为一种新型的减材加工技术,飞秒激光在材料微加工中具有独特优势。介绍了飞秒激光加工的机理,分析了飞秒激光加工效率和加工质量的影响因素,阐述了飞秒激光加工工艺参量及表面质量的预测方法,对飞秒激光与增材制造的结合应用作了展望。飞秒激光加工的效率与精度影响因素众多,要真正在金属加工领域精准大规模应用这一精细技术,尚需对飞秒激光及其与不同特性金属材料间的交互作用进行更为深入系统的研究。
As a new type of subtractive processing technology,femtosecond laser has unique advantages in material micromachining.The mechanism of femtosecond laser processing was introduced,and the factors that influence the femtosecond laser processing efficiency and processing quality were analysed.The prediction method of femtosecond laser processing parameters and surface quality was expounded.The combined application of the femtosecond laser and additive manufacturing was thenprospected.There are many factors affecting the efficiency and accuracy of femtosecond laser processing.To truly apply this fine technology on a large scale in the field of metal processing,more in-depth study of the system of femtosecond laser and its interaction with the different properties of the metal material is still needed.
