Fuzzy Analytic Hierarchy Process (FAHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) approaches were employed to predict the sawability of a diamond frame saw to cut granites. FAHP is used to determine the weights of the criteria of decision-makers and TOPSIS is used to rank sawability. The sawability was evaluated by diamond segment wear. The prediction of segment wear is important to determine the segments service life and sawing cost and may determine cutting parameter selection for a given stone. Sawing experiments were conducted to verify the analysis result of the applied method in this study. The experimental results are in good agreement with the theoretical analysis. The ranking method can be used to evaluate segment wear. Stone properties, such as uniaxial compressive strength, shore hardness, quartz content, and bending strength, must be determined for the best segment wear ranking.

“…The influences of cutting speed and depth of cut on segment wear were studied [13]. Segment wear and cutting force can be evaluated based on rock properties [14]. Shore scleroscope hardness, water absorption, and cone indenter hardness had a greater effect on segment wear than other rock properties [15].…”

“…Up to now, many studies have been done on the relations between sawability and rock characteristics in stone processing (Burgess, 1978;Wright & Cassapi, 1985;Birle & Ratterman, 1986;Jennings & Wright, 1989;Clausen et al, 1996;Tonshoff et al, 2002;Eyuboglu et al, 2003;Wei et al, 2003;Ersoy & Atici, 2004;Gunaydin et al, 2004;Kahraman et al, 2004;Özçelik et al, 2004;Delgado et al, 2005;Ersoy et al, 2005;Buyuksagis & Goktan, 2005;Kahraman et al, 2006;Fener et al, 2007;Tutmez et al, 2007;Özçelik, 2007;Buyuksagis, 2007;Kahraman et al, 2007;Mikaeil et al, 2008Mikaeil et al, , 2011aMikaeil et al, -c, 2012Mikaeil et al, , 2013aKrauze et al, 2009;Atici & Ersoy, 2009;Ataei et al, 2012).…”

The system vibration is a very significant measure of the sawing performance, because it indicates the amount of energy required to saw the rock. The maintenance cost of system is also dependant on system vibration. A few increases in system vibration cause a huge increase in the maintenance cost of the system. In this paper, the vibration of system in terms of RMSa was investigated and models for estimation of vibration by means of rock brittleness indexes and operational specifications were designed via statistical models and multiple curvilinear regression analysis. In this study, the relationships between rock brittleness indexes and operational specifications were investigated by regression analysis in statistical package for social science (SPSS) and the results of determination coefficients have been presented. In the second part, the diagrams show that a point lying on the line indicates an exact estimation. In the plot for model, the points are scattered uniformly about the diagonal line, suggesting that the models are good. It is very useful to evaluate the vibration of system and select the suitable operational characteristics by only some mechanical properties of rock.Keywords: system vibration, brittleness indexes, sawing process, statistical analysis Drgania układu uważane są za miernik wydajności procesu urabiania, ponieważ pokazują ilość energii niezbędnej do urabiania skały. Od poziomu drgań zależą także koszty eksploatacji systemu. Nieznaczny nawet wzrost poziomu drgań prowadzi do znacznego zwiększenia kosztów eksploatacyjnych urządzenia. W pracy tej przeprowadzono analizę drgań (ich wartości skutecznych) i opracowano model estymacji poziomu drgań w oparciu o współczynnik kruchości skał i parametry eksploatacyjne urządzenia. W pracy wykorzystano modele statystyczne i wielokrotną analizę metodą regresji krzywoliniowej. W pracy obecnej związek pomiędzy współczynnikiem kruchości skał a parametrami eksploatacyjnymi urządzenia badano z wykorzystaniem analizy metodą regresji dostępnej w statystycznym pakiecie oprogramowania dla nauk

“…Especially, among the previous studies some researchers have developed a number of classification systems for ranking the sawability of rocks. Wei et al (2003) evaluated and classified the sawability of granites by means of the fuzzy ranking system. In their study, wear performance of the blade and the cutting force were used as the sawability criteria.…”
