In this manner, incomes due to DS quarrying will affectively increase providing that costs of the diamond wire consumption and consequently specifi c cut (cutting planes per the unit of DS volume or weight) decrease. Therefore, in this study attempts have been made to minimize specifi c cut so that a computerized procedure is pursued.
