Recently, the studies on lightweighting have gained significant importance due to requirements such as energy efficiency and sustainability. Polymer materials are a group of materials that are frequently used for this purpose. This study investigated the effects of laser power, cutting speed and focal point on the kerf width, which are the most effective process parameters in laser cutting of Polymethylmethacrylate, a low-cost polymer material, using Response Surface Methodology and ANOVA. The results obtained from the data analysis show that the kerf width is seriously affected by the focal point depth as well as the speed and power.

Son zamanlarda enerji verimliliği ve sürdürülebilirlik gibi gereksinimler nedeniyle hafifleştirme çalışmaları büyük önem kazanmıştır. Polimer malzemeler bu amaçla sıklıkla kullanılan bir malzeme grubudur. Bu çalışmada, düşük maliyetli bir polimer olan Polymethylmethacrylate malzemesinin lazer kesiminde en etkili işlem parametreleri olan lazer gücü, kesme hızı ve odak noktasının kerf genişliği üzerindeki etkileri Yanıt Yüzey Metodu ve ANOVA kullanılarak incelenmiştir. Veri analizinden elde edilen sonuçlar, çentik genişliğinin hız ve gücün yanı sıra odak noktası derinliğinden ciddi şekilde etkilendiğini göstermektedir.
