“…In this case, a narrower and less burnt quality cut with kerf and HAZ width is obtained in the vertical cut to the fibers (the kerf width measuring axis extending in the direction parallel to the fibers) (Açık and Tutuş 2022). In another study, it was explained that the low thermal conductivity of wood compared to other engineering materials is negatively affected by hot gases that cause coal deposits on the surface of the laser-treated material and damage its texture (Aniszewska et al 2020).…”

“…Given the low thermal conductivity of wood, hot gases that cause charcoal deposits on the surface of the treated material damage the wood texture. The thickness of the carbonized layer depends on the physical properties and size of the workpiece, the processing direction (vertical and parallel to the fibers) and some laser operation parameters (Aniszewska et al 2020). Deeper understanding of the characteristic behavior of wood is essential for predicting its mechanical response, and even more so for manufacturing design if biomaterials are used.…”

“…These developments have made academic studies on laser wood processing a necessity (Guo et al 2021). On the other hand, since laser processing parameters are a versatile process, it is essential to characterize the wood mechanism in-depth and it is imperative to discover the appropriate processing combination to achieve higher yields (Aniszewska et al 2020).…”

In recent years, laser material processing technology has become quite widespread. The quality of laser processing of wood materials is very important in terms of not causing secondary processes in the production process. In this study, computerized numerical control laser cutting qualities of some wood species that are frequently used in industrial product manufacturing were investigated. In the study, 80 % irradiation and 10 mm/ sec laser cutting speed were applied to the test samples in a computerized numerical control laser machine with a 130 W carbon dioxide gas cylinder. In the case of laser cutting of 5 different wood species in the direction vertical to and parallel to the fibers, the average of the upper and lower kerf width, the difference in the width of the upper and lower kerf, the average of the width of the heat-affected zone, the width of the heat-affected zone were evaluated. In line with the findings, the effects of wood species differences on laser cutting quality in terms of material consumption, precision machining, and smoothness of cutting geometry were investigated. As a result, the highest quality cutting values were obtained from the laser cutting of the bamboo massif in terms of wood species, in the direction vertical to the fibers of the wood materials.

Lazerler gelişiminden bu yana günlük hayatımızı kolaylaştırarak günümüz teknolojisindeki ilerlemede büyük bir etkiye sahip olmuştur. İmalat sanayi lazer teknolojisinden en büyük payı almış ve birçok imalat uygulamasında tercih edilen bir teknoloji haline gelmiştir. Lazerle neredeyse bütün malzeme türüne işlem yapılabilmekte ve lazer teknolojisi endüstride markalama, kazıma ve kesme işlemlerinde yaygın olarak kullanılmaktadır. Bu çalışma markalama, kazıma ve kesme uygulamaları için düşük bütçeli bir CO2 lazer makinesinin tasarlanmasını ve üretilmesini ele almıştır. Makinenin rezonatör, optik hareket, kesim kafası ve kontrol sistemleri dahil olmak üzere tüm ana bileşenleri, ilgili okuyucuların benzer bir sistemi uygulaması için etraflıca açıklanmıştır. Makinede bulunan rezonatör, ticari olarak mevcut benzer sistemlere kıyasla ekonomik ve uzun servis ömrüne büyük bir fayda sağlayan tekrarlı gaz dolumuna izin verecek şekilde tasarlanmış ve üretilmiştir. Üretilen makine, ilk malzeme listesinden ve ilgili üretim sürecinden kauçuk, ahşap ve plastik malzemeler için yukarıda bahsedilen son uygulama örneklerine kadar açıklanmıştır. Lazer makine sistemi şu anda Karabük Üniversitesi imalat mühendisliği bölümünde kuruludur ve lisans eğitimi ve öğretimi için kullanılmaktadır. Ayrıca makine reklam, hobi, orman ürünleri, tekstil, deri ve küçük ölçekli mühendislik işlerinde orta ölçekli işletmelerin kullanımı için yeterli kapasiteye sahiptir.

The present paper deals with the analysis of cross-section surface irregularities after CO2 laser cutting. The surface irregularities of beech (Fagus sylvatica L.), oak (Quercus petraea), and spruce (Picea abies L.) wood were quantified by primary profile parameters using a digital microscope. The arithmetic mean height (Pa), used as the basic parameter, was supplemented by amplitude parameters (Pv, Pp, Pz) and the Psm parameter, through which the shape of the irregularity was specified in more detail. A statistically significant change was demonstrated when changing the values of the feed speed and the power of the CO2 laser. The results of this article confirm that the surface irregularities increased with an increasing laser power and decreasing feed rate. The scanned topographic images also provide a more detailed explanation of the measured P-parameters and point out the risks associated with the evaluation of the cross-section with the primary profile.
