Abstract

Çeşitli endüstriyel ürünlerin yüzey kalitesi son kullanıcılar yönünden önem taşımaktadır. Bu nedenle, üretim aşamasında çeşitli parametreler uygulanarak ürün yüzeyinin ilave operasyon uygulamadan uygun değer zaman içinde istenen kalitede elde edilmesi önemli rol oynamaktadır. Bu çalışmada, farklı kalınlıklarda dökme polimada 6 (PA6 G), kompozede (CFRP) ve etilen profilden dine manom er kauçuk(EPDM) malzemelerin aşındırıcı su jetinde (ASJ) farklı ilerleme hızlarında kesilmesi sonrasında malzeme kalınlığına bağlı yüzey kalitesi incelenmesi amaçlanmıştır. Toplam 99 adet kesim işleminin gerçekleştirildiği deneylerde malzeme türünün, kesme hızının ve malzeme kalınlıklarının yüzey kalitesine etkisi incelenmiştir. Polimer, kompozit ve elastomer tabanlı üç farklı malzemenin fiziksel özelliklerine göre belirlenen düşük, orta ve yüksek devirli hızlarda kesilen deney numuneleri, kesme derinliği boyunca farklı üç noktadan yüzey aşınma pürüzlüğü ölçülmüştür. Daha sonra elde dilen sonuçlar malzeme bazında ve kalınlıklarda en uygun kesme hızları karşılaştırılmıştır. Sonuç olarak, kesme hızının yüzey aşınmasının yüzey kalitesi ve farklı kalınlıklarda ve farklı malzeme yüzeylerinde işleme izlerinin varlığı üzerinde önemli bir etkiye sahip olduğu gösterilmiştir.

Experimental investigation of the parameters affecting the surface roughness of materials with different thicknesses by abrasive water jetting: Polymer, composite and elastomer materials

Abstract

The surface quality of various industrial products is important for end users. For this reason, it plays an important role to obtain the desired quality of the product surface in optimum time without additional operation by applying various parameters during the production phase. In this study, it was aimed to investigate the surface quality of cast polyamide 6 (PA6 G), composite (CFRP) and ethylene propylene diene manomer rubber (EPDM) materials of different thicknesses after cutting at different feed rates in abrasive water jet (AWJ). In the experiments where a total of 99 cutting operations were carried out, the effect of material type, cutting speed and material thickness on surface quality was analysed. The test specimens were cut at low, medium and high speeds determined according to the physical properties of three different polymer, composite and elastomer based materials and the surface wear roughness was measured at three different points along the depth of cut. The results obtained were then compared with the optimum cutting speeds for different materials and thicknesses. As a result, it has been shown that the cutting speed has a significant effect on the surface quality of the surface wear and the presence of machining marks on different thicknesses and different material surfaces.
