Aim of study: The aim of this study was to determine the effects of cutter parameters on the energy consumption of CNC machine, and surface roughness of medium density fiberboard (MDF). Material and methods: Experiments were conducted using a three-axis CNC router. The energy consumption and surface roughness values were measured using a wattmeter (TT-Technic PM 001) and roughness tester (Mitutoyo SJ 210), respectively. The values of the Ra, Rq, and Rz roughness parameters, and energy consumption were determined. Main results: The surface roughness increased with increases in the step over and feed rate, whereas the energy consumption decreased. In addition, the energy consumption increased when a high spindle speed was used. When the spindle speed is increased from 8000 rpm to 16000 rpm, the energy consumption increases by 154%. When the stepover is increased from 20% to 60%, energy consumption is reduced by 63%. When the feed rate is increased from 3 m/min to 7 m/min, the energy consumption is reduced by 60%. Highlights: The energy consumption increased as the step over and feed rate decreased. The energy consumption increased as the spindle speed increased. The surface roughness increased with the step over and feed rate

Solid wood and wood-based composite panels are used to produce different types of furniture. In the connection points of furniture, some different types of fasteners, such as screws, minifix, and dowels, are used to assemble the parts of the furniture. Melamine-faced fiber board (MF-FB) and melamine faced particle board (MF-PB) are used extensively in the production of furniture. In this study, we determined the screw withdrawal strength and screw head pullthrough of MF-FB and MF-PB. Tests were conducted on the surfaces and edges according to ASTM D1037-12. The data that were obtained indicated that the screw holding capacity of MF-PB was greater than that of MF-FB. Also, the screw holding capacity was greater on the surfaces of both MF-PB and MF-FB than it was on the edges. In addition, screw head pull-through was greater than that of direct screw withdrawal in both MF-PB and MF-FB.

Geçmişten günümüze, özellikle iç mekânlarda kullanılan mobilyalarda ve zeminlerin, duvarların ve tavanların kaplanmasında ahşap esaslı malzemeler fazlaca kullanılmıştır. Ahşap malzemenin bu şekilde tercih edilmesinin önemli sebepleri, doğal bir ürün olması, kolay işlenebilmesi, ucuz olması ve kolayca tedarik edilmesidir. Zeminlerde kullanılan ahşap malzemelerde ise, özellikle aşınma ve çizilme direncinin yüksek olması, sertliğinin yüksek olması aranmaktadır. Günümüzde, masif ağaç parke, rabıta, lamine parke, laminat parke ve marketri parke şeklinde birçok farklı tipte ahşap esaslı zemin döşeme malzemesi bulunmaktadır. Marketri parke, çok estetik bir görüntüye sahiptir ve diğer parkelerle karşılaştırıldığında oldukça pahalıdır. Bu nedenle, sadece yüksek gelir grubundaki tüketiciler zemin döşemesi için marketri parkeyi tercih etmektedir. Bunun yanında, çoğu tüketici marketri parke hakkında yeterli bilgiye sahip değildir. Bu çalışmada, marketri parkenin üretimi, uygulanması ve diğer ahşap parkelerle karşılaştırılması ve ayrıca Türkiye'de üretim miktarı hakkında bilgi verilmiştir. Bu amaç doğrultusunda, Türkiye'deki marketri parke üreticilerinden anket yöntemi ile bilgi toplanmıştır. Elde edilen bilgiler karşılaştırmalı olarak verilmiştir. Anahtar Kelimeler: Marketri parke, parke çeşitleri, stil parke A research on the production, application of marquetry parquet and comparison with other wooden parquet AbstractWood-based materials have been used extensively in the past, especially in the furniture used in the interior and in the covering of floors, walls and ceilings. The main reasons for preferring this type of wood material are the natural product, easy processing, cheapness and easy procurement. Especially for wood materials that are used in the floors, high density, high abrasion resistance and scratch resistance are required. Today, there are many different kinds of wood based flooring materials in the form of solid wood parquet, floor planks, laminated parquet, laminate parquet and marquetry parquet. The marquetry parquet has a very aesthetic appearance and is quite expensive compared to other parquet. For this reason, only the consumers in the high income group prefer the marquetry parquet for flooring. Besides, most consumers do not have enough knowledge about marketing parquet. In this study, the production of marquetry parquet, implementation and comparison with other parquet and has also tried to provide information about the amount of production in Turkey. For this purpose, the questionnaire information method from marquetry parquet manufacturer in Turkey was collected. The information obtained is given comparatively.
