Production process in dimension stone quarries has a close relationship with the diamond beads efficiency and their number in unit length (density parameter). This study intends to find out the governing relationship between these parameters and cutting efficiency according to empirical findings in Targh travertine quarry. In addition, it’s been tried to figure out the optimum operating condition in order to maximize the efficiency. To do so, along with the number of beads in unit length, other parameters such as cutting length and time have been recorded through the whole lifetime of cutting wire. The collected data have been compiled statistically in order to obtain the optimum cutting dimensions, cutting capacity and efficiency and the optimum number of beads in unit length. The results showed that the optimum mode of cutting wire assembly occurs using 31 diamond beads per meter. Besides, diamond beads have the highest efficiency at the middle third of their lifetime.

Key words: diamond bead, dimension stone, travertine quarry, cutting efficiency.
