Numerical Simulation of Fragment Separation during Rock Cutting Using a 3D Dynamic Finite Element Analysis Code

Figure 8

The cutting results for a cutting depth of 6 mm and a cutter speed of 3 m/s: (a), (c), (e), and (g) are the cutting results for sandstone-1, sandstone-2, sandstone-3, and limestone, respectively, and (b), (d), (f), and (h) are the variation in the cutting force with distance for sandstone-1, sandstone-2, sandstone-3, and limestone, respectively.
