Abstract
This study investigates the wear performance of diamond circular saw blades in cutting of granitic rocks An alternative wear measuring method is developed to measure the reduced blade radius without taking the blade off the machine The effect on and contribution to the specific wear rate SWR of each operating variable are determined and the SWR is correlated with rock properties Morphologies of wearing surfaces of segments and rocks are also evaluated using scanning electron microscopy SEM Depending on both operating variables and rock properties prediction models are developed for estimation of the SWR Results show that the SWR increases with an increase in the peripheral speed and the traverse speed while it decreases with an increase in the cutting depth and the flow rate of the cooling fluid The peripheral speed and the microhardness and proportions of minerals such as quartz plagioclase and feldspar are statistically determined as the significant variables affecting the SWR Finally it is disclosed that models developed for estimation of SWR have great potential for practical applicationsThe authors would like to thank the Scientific Research Fund of Karadeniz Technical University for financial support of this work no 20091120083 Additionally the authors are most grateful to Granitaş AŞ stone processing company for supporting this research by providing dimensioned rock samples for the sawing experiments
