Abstract

Fiberboard is used extensively in furniture production in all over the
word. One of the most important reasons for the preference of fibreboard is the
easy shaping of its surfaces. In the past, the surfaces of the fiberboard were
processed using conventional machines. Nowadays, Computer Numerical Control
(CNC) machines are used in the processing of the fiberboard. CNC machines is
operated using some computer control commands which provide the action of the
machine. The code file consisting of
these commands contains some adjustments such as step over, spindle speed, feed
rate, finish depth, machining strategy, step down, plunge rate etc. These
adjustments change the surface roughness of the processed section of fiberboard.
In this study, the influence of finish depth (2 and 6 mm), step over (40%, 60%
and 80%) and feed rate (3, 5 and 7 m/min) settings on the surface roughness of fiberboard
were investigated. Ra roughness value
of processed section of fiberboard test samples was determined using contact
stylus method. According to the obtained
data, it was concluded that the surface roughness increased as finish depth,
feed rate and step over are increased.

Abstract

Lif levha tüm dünyada mobilya üretiminde büyük miktarlarda
kullanılmaktadır. Lif levhanın tercih edilmesinin en önemli nedenlerinden biri
yüzeyinin kolay şekillendirilmesidir. Geçmişte, Lif levhaların yüzeyleri
konvansiyonel makinelerle işlenmiştir. Günümüzde, Bilgisayar Sayısal Kontrol
(CNC) makineleri lif levhaların işlenmesinde kullanılmaktadır. CNC makineleri,
makinenin hareketini sağlayan bilgisayar kontrol komutları kullanılarak
çalıştırılmaktadır. Bu komutlardan oluşan kod dosyaları, bıçak adımı, bıçak
motoru hızı, besleme hızı, kesme derinliği, işleme taktiği, bıçak dalma
derinliği, dalma hızı gibi birçok ayarlamaları içermektedir. Bu ayarlamalar, lif
levhanın işlenen kısmının yüzey pürüzlülüğünü değiştirmektedir. Bu çalışmada,
kesme derinliği, (2 mm ve 6 mm) bıçak adımı (%40, %60 ve %80) ve besleme hızı
(3, 5 ve 7 m/min) ayarlarının lif levhanın yüzey pürüzlülüğü üzerine etkileri
araştırılmıştır. Lif levha test örneklerinin işlenen kısımlarının Ra pürüzlülük değeri iğne taramaları
temas yöntemi kullanılarak belirlenmiştir. Elde edilen verilere göre; kesme
derinliği, besleme hızı ve bıçak adımı arttıkça yüzey pürüzlüğünün arttığı
belirlenmiştir.
