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

Öz

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 were made 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 at tangential 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 without planing. This will provide economic benefits to
producers.
