“…CNC machine is used to process natural stone blocks and wastes in 3D design products to be used in buildings. Many studies have been found on the C f in circular saws depending on the physicomechanical properties of natural rocks, modeling of the S e and socket [19][20][21][22][23], the definition of the theoretical chip geometry [24], and connections between tangential cutting force and chip thickness [25][26][27]. Some other studies address the effect of processing parameters on tool wear [28][29][30][31], the modeling of natural stone cutting with diamond cutting tools [32] and specific grinding energy of chip samples under a scanning microscope [33] in order to determine specific cutting energy and power consumption [34,35].…”

This study used a four-axis computer controlled machine to determine the cutting forces (C f), specific cutting energy (S c) and specific energy (S e) affecting the processability of natural rocks. A total of 17 types of natural rocks were categorized according to their geological formations. This study consisted of three parts: (1) experimental measurement of the C f resulting from processing natural rocks using a 6.0-mm diameter end mill cutting tool and a four-axis machine; (2) calculation of C f ,S c and S e values; and (3) statistical analysis of the parameters. In terms of C f ,S c and S e values, a statistically significant difference (P < 0.001) was observed among a depth of cut (d p) and feed speed (V a). It was found that the parameters that affected the processability of natural rocks were d p and V a. Accordingly, the processability of natural rocks processing type, d p and V a was found that affected. Simple linear regression was performed to examine the relationship between physicomechanical properties, and between C f ,S e and S c values. As a result, regression equations were developed in consideration of the physicomechanical properties of natural rocks and the C f ,S c and S e equation for the prediction of the efficiency of computer numerical control (CNC) machines.

“…Wear of saw blades is an important parameter affecting the economy of the cutting process, which can provide a significant saving when controlled effectively. The wear can be defined as a mass loss of diamond tool while interacting with the rock [4,[17][18][19][20][21]. The wear mechanism of a segment is governed by the mechanical interaction between the rocks and cutting tools.…”

“…Additionally, it was seen that the SWR index was related to Rosiwal hardness of these minerals and the maximum particle size of the feldspar. Bayram [17] examined the relationships between the saw-blade wear and some rock properties. The researcher found that the sawblade wear decreased with the increase of Böhme surface abrasion.…”

Saw blades are one of the most used cutting tools. They compose the expensive parts of a cutting machine. Therefore, saw-blade wear is an important parameter governing the economy of the cutting process. Significant savings could be made when it is controlled effectively. In this study, a new methodology is employed for the determination of the saw-blade wear in the cutting of two types of marble. Wear of segments is determined by high-precision inductively coupled plasma method. Two types of marbles were used to investigate the wear performance of diamond-impregnated segments of circular saw-blade matrix. Taguchi mixed design L16 (4 3 2 1) is used as an experimental design and the results are evaluated statistically with Minitab. The results reveal that the specific wear rate (SWR) of Beige marble increases with the increase of the peripheral speed, traverse speed, depth of cut and down-cut mode operation. Additionally, it is demonstrated that the traverse speed and peripheral speed are the dominant cutting parameters affecting the SWR. It is also seen that similar trends are observed for Onyx marble (excluding peripheral speed). Finally, it is concluded that the proposed models can be effectively used for the estimation of the SWR.

Bu çalışmada, bilgisayar kontrollü makine (CNC) ile mermerlerin işlenebilirliğinde kesme kuvveti ve spesifik enerjisi belirlenmiştir. Piyasada yaygın olarak kullanılan ve oluşumlarına göre sınıflandırılmış, 5 farklı tür mermer üzerine araştırma yapılmıştır. Deneysel çalışmalarda, parmak frezeli kesici uç (6.0 mm) ile farklı işleme türü (dış hatlar ve çizgisel), kesme derinliği (1.2, 1.6 ve 2.0 mm), ilerleme hızı (2000, 2500 ve 3000 mm/dk) parametreleri seçilmiştir. Bilgisayar kontrollü makine ile yapılan işlenebilirlik deneylerinde işleme türü, kesme derinliği ve ilerleme hızına göre Fz, Fc ve Ft kuvvetleri ve spesifik enerji değerlerinin istatistiksel analizi yapılmıştır. Mermerlerin kuvvet değerleri ve spesifik enerji değerleri bakımından p<0.001 anlamlılık düzeyinde işleme türü, kesme derinliği ve ilerleme hızı arasında istatistiksel olarak anlamlı fark bulunmuştur. Sonuç olarak bu çalışmada, işleme türü, kesme derinliği ve ilerleme hızının işlenebilirliği etkilediği belirlenmiştir.
