Effect of cutting parameters on consumed power in industrial granite cutting processes performed with the multi-disc block cutter

• Multi-blade block cutter working parameters were investigated.
• Stone cutting processes involving the cutting of large rock blocks were evaluated.
• Power consumption values associated with industrial cutting processes were analyzed.
• The differences between the down-cutting and up-cutting modes were investigated.
• The effects of cutting depth and feed rate on power consumption were investigated.

The aim of this study was to investigate the effect of the cutting mode, cutting depth, and feed rate on the level of consumed power, during granite cutting using circular saw blades. In this context, two-column multi-blade block cutters were used to evaluate twelve different cutting conditions conducted with more than three hundred cycles. In these tests performed with 1200 mm saws, the feed rates of 10, 13, 15, and 17 m/min and cutting depths of 3, 6, and 9 mm were used, while the peripheral speed was kept constant (≈35 m/s). Based on the evaluation of industrial cutting conditions involving the sawing of relatively large rock blocks with a circular saw blade, it was determined that the down-cutting mode was more advantageous in terms of power consumption. In addition, the effects of the cutting mode, cutting depth, and feed rate on the cutting efficiency and power consumption (one of the most important indicators of cutting performance) were also determined.
