摘要

本文研究了铬合金800ht的co2激光切割。对割缝中出屑的情况进行了监测，并将出屑频率与条纹频率进行了相关分析。进行了扫描电镜显微摄影和切割边缘表面粗糙度的测量。热切割的国际标准被用来评估切割边缘的质量。采用因子分析进行统计分析，以确定切割速度、激光输出强度、厚度和激光束脉冲频率对切割边缘的波幅、不平整度和整体质量的显著性水平。结果表明，出渣频率与磨粒频率直接相关。扫描电镜显微摄影、表面粗糙度测量和条纹频率监测的光学方法的结果是一致的。在一定的脉冲频率范围内，切割边缘的整体质量得到改善。

CO 2 laser cutting of Incoloy 800 HT alloy and its quality assessment

In this article CO 2 laser cutting of Incoloy 800 HT alloy is studied. The dross ejected from the kerf is monitored and the frequency of dross ejection correlated with the striation frequency. SEM microphotography and measurement of the surface roughness of the cut edges are carried out. International standards for thermal cutting are used to assess the quality of the cut edges. A statistical analysis employing a factorial analysis is carried out to determine the significance levels of the cutting speed, laser output intensity, thickness, and the pulse frequency of the laser beam for the waviness, out of flatness, and overall quality of the cut edges. It is found that the dross ejection frequency is directly related to the striation frequency. The results of SEM microphotography, surface roughness measurement, and the optical method for the striation frequency monitoring are found to be in good agreement. The overall quality of the cut edge improves within a certain range of pulsing frequency, which is ca...

期刊介绍： Lasers in Engineering publishes original (primary) research articles, reviews, short communications and letters on all aspects relating to the application of lasers in the many different branches of engineering and related disciplines. The topics covered by Lasers in Engineering are the use of lasers: in sensors or measuring and for mapping devices; in electrocomponent fabrication; for materials processing; as integral parts of production assemblies; within the fields of biotechnology and bioengineering; in micro- and nanofabrication; as well as the materials and processing aspects of techniques such as cutting, drilling, marking, cladding, additive manufacturing (AM), alloying, welding and surface treatment and engineering. Lasers in Engineering presents a balanced account of future developments, fundamental aspects and industrial innovations driven by the deployment of lasers. Modern technology has a vitally important role to play in meeting the increasingly stringent demands made on material and production systems. Lasers in Engineering provides a readily accessible medium for the rapid reporting of new knowledge, and technological and scientific advances in these areas.
