摘要

In this study, laboratory tests were carried out on 15 different volcanic and carbonate rocksrncollected from the marble processing plants to determine the specific cutting energy value in cutting operationrnwith circular saw of each rock. Circular sawing measurements were performed on a specially designed high precisionrnrock block cutter. All rock specimens used in the cutting tests were having a length of 50×100×200mmrnsection. The sawing analyses were performed in the down cutting mode. The main sawing parameters which arernperipheral speed of the saw blade (60 m/s), cutting depth (20 mm) and workpiece traverse speed (0.5 m/min) wasrnkept constant in the cutting tests. To calculate elastic parameters of rocks, the velocities of P and S-waves werernmeasured using the high frequency ultrasonic pulse technique instrument. The ultrasonic elastic parameters suchrnas modulus of elasticity, shear modulus, bulk modulus and Poisson’s ratio of rocks were calculated from thernmeasured wave velocities and the bulk density according to ASTM D 2845. Specific cutting energy and rockrnelastic properties were evaluated using simple regression analysis by statistical methods. Regression analysisrnshowed that high correlations exist between specific cutting energy and elastic parameters of rocks.
