摘　　要：在实际的生产应用中,切割质量和效率都是优先考量的重要因素。采用355 nm波长激光在厚1 mm的碳纤维板上进行切割实验,在保证切割区域自由掉落的前提下,通过单因子控制变量法探究了占空比、缝宽、光斑重叠率对切割质量和切割效率的影响规律。研究结果表明:过大或过小的参数都会影响切割的效率,其中占空比对切割效率的影响最大;切割边缘热影响和崩边量变化趋势相近,其中缝宽对截面锥度的影响最大。实验实现了热影响小于225μm、崩边量小于85μm、锥度小于0.1条件下一个2 mm×6 mm的方框切割,使其自动掉落所需要的时间最少为26.44 s。This paper investigates the critical factors influencing cutting efficiency and quality in practical production applications,focusing on the use of a 355 nm wavelength laser to cut 1mm thick carbon fiber plates.Under the premise of ensuring the free drop of the cutting area,the single factor control variable method was used to explore the effects of duty cycle,slit width and spot overlap rate on cutting quality and cutting efficiency.The results show that the extreme parameter values negatively affect cutting efficiency,with the duty cycle ratio exerting the most significant impact.The thermal impact on the cutting edge is similar to the trend of the amount of edge collapse,while the greatest impact on the cross-sectional taper is the change in seam width.Under the condition that the thermal impact is less than 225μm,edge collapse is less than 85μm,and the taper is less than 0.1,the minimum time required to make it fall automatically is 26.44 s.
