Kesiş Yönü ve Zımpara Tanecik Sayısının Sarıçam (Pinus sylvestris L.) ve Doğu Kayını (Fagus orientalis L.) Odunlarının Yüzey Pürüzlülüğüne Etkilerinin Belirlenmesi
Çalışmanın amacı: Bu çalışmada; zımparalanmış sarıçam ve doğu kayını odunlarında, kesiş yönü ve zımpara çeşidinin yüzey kalitesine etkileri araştırılmıştır. Materyal ve Yöntem: Denemeler için mobilya sanayisinde en çok kullanılan sarıçam ve Doğu kayını odunları seçilmiştir. Örnekler 40, 60 ve 80 kum, 3 farklı zımpara ile zımparalanmıştır. İşlenen numunelerin yüzey düzgünlük ölçümleri TS 2495 EN 3274 ve TS 6956 EN ISO 4287 esaslarına göre yapılmıştır. Yüzey düzgünlük ölçümlerinin değerlendirilmesinde, iğne taramalı ölçme yapan Mitutoyo Surfest SJ-301 cihazı kullanılmıştır. Denemeler için 36 adet test numunesi kullanılmış ve her örnek 8 eşit parçaya bölünerek bu bölümlerden liflere dik yönde ve 20 mm boyunda iki ölçme yapılmıştır. Sonuçlar: Deney sonuçlarına göre en düzgün yüzey; sarıçam odununda, teğet yüzeyde, 80 numaralı zımpara ile elde edilmiştir. En pürüzlü yüzey ise; doğu kayını odununda, teğet yüzeyde, 40 numaralı zımpara ile elde edilmiştir. Araştırma Vurguları: Özellikle ahşap mobilya imalatında; ağaç malzemeler daire testerelerle biçildikten sonra, rendeleme işlemi yapılmadan 60 ve 80 kum zımparalarla zımparalanarak düzgün yüzeyler elde edilebilir. Bu durum üreticilere ekonomik fayda sağlayacaktır
Determination of the Effect of Cutting Direction and Grit Sizes of the Abrasive on Surface Roughness of Scotch Pine (Pinus sylvestris L.) and Oriental Beech (Fagus orientalis L.) Woods
Aim of the study: In this study; effects of the grit size of abrasive and cutting direction on surface quality of sanded Scotch pine and Oriental beech woods were investigated.Material and Methods; Scotch pine and Oriental beech which are commonly used in furniture sector were chosen. Specimens were sanded with three different grit sizes of abrasives; namely, 40, 60, and 80- grit. The surface roughness of specimens was measured using Mitutoyo Surfest SJ-301 stylus scanner device on the basis of TS 2495 EN 3274 and TS 6956 EN ISO 4287. In total, 36 test samples were used for the experiments and each specimen was divided into eight equal parts and two measurements weremade perpendicular to grain at 20 mm length.Main results: The smoothest surface was obtained from the Scotch pine when sanded at tangential section with 80-grit abrasives. The roughest surface was obtained from the Oriental beech when sanded attangential section with 40-grit abrasives.Highlights: Especially, in the production of wooden furniture; after the wood materials are cut with circular saws, smooth surfaces can be obtained by sanding them with a 60 and 80-grit abrasives withoutplaning. This will provide economic benefits to producers
