Abstract

Precision cutting of the acrylonitrile–butadiene–styrene (ABS) film by ultraviolet (UV) picosecond laser can expand its applications. However, the cutting mechanism is unclear, and the cutting process needs to be optimized. ABS film was cut by a 355 nm picosecond laser with a maximum power of 30 W to study its mechanism and process. On the one hand, a laser material interaction mechanism analysis method based on the simulation and characterization of byproducts is proposed. The mechanism is dominated by photochemical reaction and synergized by the photothermal effect. On the other hand, a cutting quality evaluation system is established to explore the influence of processing parameters on processing quality through orthogonal tests. Based on the cutting mechanism, a cutting process optimization method is developed by suppressing the thermal effect through cutting speed and power. When the parameter combination was set to 80 mm/s-1.63 W-3 times (cutting speed, laser power, and repetition number of laser cutting), a narrow kerf (26.4 ± 3.2 μm) and HAZ (25.3 ± 2.8 μm) were obtained. This result indicates that UV picosecond laser cutting of ABS films exhibits micron-level precision, making it suitable for manufacturing precision components in the electronics and aerospace sectors.

紫外皮秒激光对ABS薄膜进行精密切割

利用紫外皮秒激光对丙烯腈-丁二烯-苯乙烯（ABS）薄膜进行精密切割，可以扩大其应用范围。但切削机理尚不清楚，切削工艺有待优化。采用最大功率为30w的355nm皮秒激光切割ABS薄膜，研究其切割机理和工艺。一方面，提出了一种基于副产物模拟和表征的激光材料相互作用机理分析方法。其机理以光化学反应为主，光热效应协同作用。另一方面，建立了切削质量评价体系，通过正交试验探讨了加工参数对加工质量的影响。根据切削机理，提出了一种通过切削速度和功率抑制热效应的切削工艺优化方法。当参数组合设置为80 mm/s-1.63 W-3次（切割速度、激光功率、激光切割重复次数）时，可获得窄切口（26.4±3.2 μm）和HAZ（25.3±2.8 μm）。这一结果表明，UV皮秒激光切割ABS薄膜具有微米级的精度，适用于制造电子和航空航天领域的精密部件。
