· According to the relative motion between the rock and the cutter, rock cutting experiments are generally divided into three categories: linear cutting, rotary cutting, and hybrid cutting. A linear cutting test is the most convenient and direct method for studying the interactions between a cutter and rock ( Che et al., 2017 ).

The most effective method for cutting rough stones is to break the rock with a rock hammer. As you might suspect from the name, the process is quite simple: you take a large, uncut stone, and hit it hard with a rock hammer. We should mention that this method doesn't emphasize precision. Instead, the goal is to make large breaks in rough stones.
