An experimental study was performed to investigate effects of operating variables on the cutting force (CF) acting on diamond sawblade in stone sawing. Multi-variable linear regression analysis was also carried out to determine dominant operating variables affecting the CF. In the experimentations, a computer controlled block cutter was used and the experiments were performed with the same-direction cutting mode. The results showed that higher CFs were obtained for higher cutting depth and traverse speed, and for lower peripheral speed and flow rate of cooling fluid. The cutting depth was determined as the most significant operating variable affecting the CF.
