Stress and Wear Analysis of the Disc Cutter of Rock Tunnel Boring Machine The Open Mechanical Engineering Journal, 2015, Volume 9 723 Fig. (3). The distribution of stress on the edge of disc cutter. From the Fig. (3) it can be seen that the value of stress on contact area between the disc cutter and the rock is maximum.
Tunnel Boring Machine (TBM) is an effective machine for building hard-rock tunnel. However, the interaction between the cutter of TBM and rock is the key factor before engineering construction, which will cause a lot of unnecessary losses and trouble in the construction process.
Tunnel Boring Machine (TBM) A tunnel boring machine (TBM) ... All types of hard rock TBMs excavate rock using disc cutters mounted in the cutter head. The disc cutters create compressive stress fractures in the rock, causing it to chip away from the rock in front of the machine, called the tunnel face. ... Behind all types of tunnel boring ...
