Abstract

Polymers provide superior strength-to-weight ratios, malleability, cost-effectiveness, and recyclability compared to metals and alloys, rendering them highly favoured in the domains of automobile, electrical, medicinal, and thermal engineering. The present study employs a fiber laser as an approach to generate Gaussian beam-shaped micro-channels on thick transparent PMMA material while being submerged in de-ionized water to mitigate the problems associated with infrared laser micro-channeling such as non-uniformity, combustion and region of altered properties due to heat. Micro-channel quality is assessed by measuring three key metrics: depth of cut, kerf width, and heat-affected zone. This analysis considers power, cutting speed, and pulse frequency. The laser transmission channelling experiment is conducted on PMMA employs a central composite rotatable experimental strategy. The optimal settings are set to have a depth of cut of 25.34 µm, a kerf width of 4.98 µm, and a HAZ width of 36.32 µm.

水介质中厚 PMMA 的光纤激光微通道性能参数评估

与金属和合金相比，聚合物具有更高的强度重量比、延展性、成本效益和可回收性，因此在汽车、电气、医药和热能工程领域备受青睐。本研究采用光纤激光器在厚透明聚甲基丙烯酸甲酯材料上生成高斯光束形微通道，同时将其浸没在去离子水中，以缓解红外激光微通道相关问题，如不均匀性、燃烧和因热而改变特性的区域。微通道质量通过测量三个关键指标来评估：切割深度、切口宽度和热影响区。该分析考虑了功率、切割速度和脉冲频率。在 PMMA 上进行的激光传输通道实验采用了中央复合可旋转实验策略。最佳设置为切割深度为 25.34 微米，切口宽度为 4.98 微米，热影响区宽度为 36.32 微米。

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
