Cam elyaf takviyeli polimer (CETP) kompozit malzemeler sahip oldukları üstün özelliklerinden dolayı yeni ve önemli mühendislik malzemeleridir. Mekanik özellikleri, rijitlik/ağırlık oranlarından dolayı özellikle hafiflik istenilen mühendislik yapılarında vazgeçilmez yapısal malzemelerdir. Bu sayede CETP kompozit malzemeler endüstride sıklıkla kullanılmaktadır. Delme işlemi endüstride CETP kompozitlerin montajı için gerekli deliklerin elde edilmesinde en önemli prosestir. Delik kalitesine kesme parametrelerinin yanı sıra matkap geometrisinin etkisi de ele alınmalıdır. Bu çalışmada, farklı kesme parametreleri (kesme hızı, ilerleme) ve matkap geometrileri (farklı çaplar) ile delme işlemi gerçekleştirilmiştir. İtme kuvveti ile giriş ve çıkış yüzeyleri için deformasyon faktörü sonuçları elde edilmiştir. Ayrıca kesme parametrelerinin sonuçlara olan etkilerinin belirlenmesi için Taguchi metodu ve varyans analizi kullanılarak analiz yapılmıştır. Taguchi analizi için L9(313) ortogonal deney tasarımı seçilmiş ve cevap tabloları kullanılmıştır. İtme kuvveti ve çıkış deformasyon faktörü için ilerlemenin, giriş deformasyon faktörü içinse matkap çapının daha etkin parametre oldukları tespit edilmiştir. Sonuçlar, CETP kompozit malzemelerin delinmelerinde bu yaklaşımın etkin bir şekilde uygulanabileceğini göstermiştir.

Experimental investigation of CETP composites with wooden drilling performance

Öz

Glass fiber reinforced polymer (CETP) composite materials are new and important engineering materials due to their superior properties. Due to their mechanical properties, rigidity / weight ratio, they are indispensable structural materials, especially in engineering structures where lightness is required. Therefore, GFRP composite materials are commonly used in industry. Drilling is an important process for obtaining the holes which is necessary for the assemblies of GFRP in industry. In addition to drilling parameters, the impact of drill geometry on the hole quality should be considered. In this paper, drilling process was carried out with different cutting parameters (cutting speed, feed rate) and drill geometries (different diameters). The obtained the results of thrust force and deformation factor for exit/entrance surface. Taguchi method and analyze of variance (ANOVA) was also applied to determine the effects of cutting parameters on experimental results. L9(313) orthogonal experimental design was selected for analysis of Taguchi and response Tables was used. Besides the cutting parameters, the impact of drill geometry on the results are also discussed. It is obtained that feed rate governs the thrust force and exit deformation factor; however, the entrance deformation is driven by the drill bit diameter. The results show that this approach has been demonstrated can be used effectively for drilling of GFRP composite materials.
