Abstract

In the stone processing industry, sawing rate and sawblade life are the main parameters economically affecting the process. However, the relative importance ranking of these parameters may vary depending on the needs and priorities of the plant. In this study, utilizing a fully instrumented circular side-cutting machine, the effect of sawing rate on force and energy requirements of two selected granite types were investigated. It was concluded that, when it is intended to achieve higher sawing rates, employing a higher feed velocity and a shallower cutting depth improves the efficiency of the process in terms of cutting forces, power and specific energy. However, the magnitude of this improvement varies according to the mineralogical properties of the tested rock.
