Abstract: Tunnel boring machines (TBMs) are large-scale mechanical devices that play an essential role in the
construction of various underground infrastructures, including transportation tunnels, water conservancy projects and
hydropower facilities. TBMs are engineered to efficiently excavate through a variety of geological conditions, making
them indispensable in modern civil engineering and construction projects. One of the critical components of a TBM is
the disc cutter, which is responsible for the rock-cutting process. The performance and longevity of cutters are vital for
the overall efficiency of the TBM, as they directly influence the rate of excavation and the quality of the tunnel being
