摘要
激光切割是一个复杂的过程。为了研究光纤激光对304不锈钢薄板切割质量的影响,发现工艺参数对切割指标的影响规律,得到最优切割工艺参数,本文利用光纤激光器对1mm、2mm、3mm厚度的304不锈钢进行了激光切割实验。通过软件设计实验、板材切割、数据采集、软件分析等过程,利用三维曲面表达结果。实验表明:挂渣量的多少主要取决于焦点与功率,且两者都存在一个最佳范围;切缝宽度的大小主要取决于板厚与功率;粗糙度的大小主要取决于功率和焦点,两者也存在一个最佳范围;条纹间距主要取决于气压和功率,最终得到切割3种不同厚度板材的最优参数。
The fiber laser resource has been adopted to conduct laser cutting test to the 304 stainless steel sheets with 1mm, 2mm, and 3mm thickness in the text.Through software designing test, sheet cutting, data collecting, and software analysis process, the results have been expressed by use of three-dimension shape. The test shows that adhering slag quantity depends on focal point and power, both of which have one best range; the size of kerf width primarily depends on sheet thickness and power; the roughness chiefly depends on the power and focal point, both of which have a best range; the fringe gap depends on air pressure and power. Finally, the optimized parameters for the sheet with three different thickness have been obtained.
