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.
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.
