Abstract

Bu çalışma, termoplastik malzemelerin CO2 lazer kesiminde bir dizi girdi parametresinin (malzeme tipi, güç ve kesme hızı) kritik çıktı parametreleri (kerf genişliği ve ısıdan etkilenen bölge) üzerindeki etkilerini araştırmayı amaçladı. Lazer kesim işlemi, Taguchi L18 (21x32) ortogonal dizi tasarımına göre gerçekleştirilmiştir. Kesme parametrelerinin çıktılar üzerindeki etkileri, sinyal-gürültü (S/N) oranı ve varyans analizi (ANOVA) teknikleri kullanılarak belirlendi. Ayrıca, kerf genişliği ve ısıdan etkilenen bölge tahmini için regresyon analizi kullanılarak birinci ve ikinci dereceden matematiksel modeller oluşturulmuştur. Kerf genişliği ve ısıdan etkilenen bölge için optimum lazer kesim parametreleri Polivinil Klorür (PVC) malzeme cinsi, 80 W güç ve 15 mm/s kesme hızı olarak belirlenmiştir. ANOVA sonuçları incelendiğinde, kerf genişliği üzerindeki en etkili parametrenin %53,99 ile kesme gücü ve ısıdan etkilenen bölge üzerindeki en etkili parametrenin ise %40,96 ile malzeme tipi olduğu görülmüştür. Kerf genişliği ve ısıdan etkilenen bölge için oluşturulan regresyon denklemlerin belirtme katsayı (R2) değerlerinin oldukça yüksek olduğu tespit edilmiştir.

Statistical Investigation of the Effect of CO2 Laser Cutting Parameters on Kerf Width and Heat Affected Zone in Thermoplastic Materials

Abstract

Understanding and optimizing the CO2 laser cutting process of thermoplastic materials is critical for improving product quality, reducing waste, and achieving efficient manufacturing processes. This study aimed to investigate the effects of a number of input parameters (i.e., material type, power, and cutting speed) on the key output parameters (i.e., kerf width and heat affected zone) in CO2 laser cutting of thermoplastic materials. The laser cutting process was performed based on the Taguchi L18 (21x32) orthogonal array design. The effects of cutting parameters on the outputs were calculated by using the signal-to-noise (S/N) ratio and analysis of variance (ANOVA) techniques. Furthermore, first and second-degree mathematical models were established by using regression analysis to estimate the values of kerf width and heat affected zone. The optimum laser cutting parameters for kerf width and heat affected zone were determined as and Polyvinyl Chloride (PVC) material type, 80 W power, and 15 mm/s cutting speed. The ANOVA results showed that the most efficient parameter on kerf width was power with 53.99% while the most efficient parameter on heat affected zone was material type with 40.96%. In addition, the coefficient of determination (R2) values for the regression equations developed for the outputs are significantly high. The R2 values of the first- and second-degree regression equations for KW are 97.26% and 99.71%, respectively, whereas 93.43% and 98.18% for HAZ.
